   I was not able to completely solve this issue, but some of it

   this code will resolve the color problem of the above issue with little modifications in the updateSurfaceplot.m file

   %-------------------------------------------------------------------------%
   
   bar3 = false;
   
   try
       if (isfield(image_data, 'Tag') && strcmp(image_data.Tag, 'bar3'))
           bar3 = true;
       end
   catch
       %TODO
   end
   
   %-------------------------------------------------------------------------%
   
   %-------------------------------------------------------------------------%
   
   %-image colorscale-%
   
   cmap = figure_data.Colormap;
   len = length(cmap)-1;
   
   if bar3
       faceColor = image_data.FaceColor;
       if isnumeric(faceColor)
           color = 255*faceColor;
           for c = 1: length(cmap)
               obj.data{surfaceIndex}.colorscale{c} = { (c-1)/len , ['rgb(' num2str(color(1)) ',' num2str(color(2)) ',' num2str(color(3)) ')'  ]  };
           end
       else
           switch faceColor
               case 'none'
                   color = [255, 255, 255]; %TODO
                   for c = 1: length(cmap)
                       obj.data{surfaceIndex}.colorscale{c} = { (c-1)/len , ['rgb(' num2str(color(1)) ',' num2str(color(2)) ',' num2str(color(3)) ')'  ]  };
                   end
               case 'flat'
                   scalefactor = (surfaceIndex - figure_data.CurrentAxes.CLim(1))/diff(figure_data.CurrentAxes.CLim);
                   color =  255*(cmap(1 + floor(scalefactor*(length(cmap)-1)),:));
                   for c = 1: length(cmap)
                       obj.data{surfaceIndex}.colorscale{c} = { (c-1)/len , ['rgb(' num2str(color(1)) ',' num2str(color(2)) ',' num2str(color(3)) ')'  ]  };
                   end
           end
       end
       
   else
       for c = 1: length(cmap)
           col = 255 * cmap(c, :);
           obj.data{surfaceIndex}.colorscale{c} = { (c-1)/len , ['rgb(' num2str(col(1)) ',' num2str(col(2)) ',' num2str(col(3)) ')'  ]  };
       end
   end
   

   and this code will fix the bar positions in the same file-

   %-aspect ratio-%
   ar = obj.PlotOptions.AspectRatio;
   
   if ~isempty(ar)
       if ischar(ar)
           obj.layout.scene.aspectmode = ar;
       elseif isvector(ar) && length(ar) == 3
           xar = ar(1);
           yar = ar(2);
           zar = ar(3);
       end
   else
   
       %-define as default-%
       xar = max(x(:));
       yar = max(y(:));
       zar = 0.7*max([xar, yar]);
   end
   
   obj.layout.scene.aspectratio.x = xar;
   obj.layout.scene.aspectratio.y = yar;
   obj.layout.scene.aspectratio.z = zar;
   
   %---------------------------------------------------------------------%
   
   %-camera eye-%
   ey = obj.PlotOptions.CameraEye;
   
   if ~isempty(ey)
       if isvector(ey) && length(ey) == 3
           obj.layout.scene.camera.eye.x = ey(1);
           obj.layout.scene.camera.eye.y = ey(2);
           obj.layout.scene.camera.eye.z = ey(3);
       end
   else
   
       %-define as default-%
       xey = - xar; if xey>0 xfac = -0.2; else xfac = 0.2; end
       yey = - yar; if yey>0 yfac = -0.2; else yfac = 0.2; end
       if zar>0 zfac = 0.2; else zfac = -0.2; end
       
       obj.layout.scene.camera.eye.x = xey + xfac*xey; 
       obj.layout.scene.camera.eye.y = yey + yfac*yey;
       obj.layout.scene.camera.eye.z = zar + zfac*zar;
   end
   % 
   % xey = figure_data.CurrentAxes.DataAspectRatio(1);
   % yey = figure_data.CurrentAxes.DataAspectRatio(2);
   % zey = figure_data.CurrentAxes.DataAspectRatio(3);
   %---------------------------------------------------------------------%
