Multi-Plot Problem during Multi-Aperture process

I have been learning the process of multi-aperture photometry in AstroImageJ and made some process. When first doing multi-aperture process on a single image, and I finished, the windows for doing the multi-plot would routinely pop up. I didn't (at that time) know what to do with them, so routinely closed them. This happened for many iterations.

The Problem: Now, as I have started to explore the multi-aperture process on a stack (9 slices), somewhere along the way the multi-plot windows did not open when I finished selecting the target star and comp stars (1 target, 6 comps) on first image in stack. I do get the measurement window, but no multi-plot windows pop up. Clicking on the multi-plot icon on the normal ImageJ command bar yields the following error window:



Using the Analyze-MultiPlot command I get this error:



So, I don't know why multi-plot is not working in general, and why it stopped working after working initially. Can anyone help? (I've tried deleting and reinstalling AstroImageJ - no effect).

I've also experienced some instances in which clicking on the multi-aperture icon causes the science image to disappear from the desktop. It's listed in the "Window", but nothing I tried would make the image visible. I could close image using menu commands, and could open image, but clicking on multi-aperture caused the image to disappear. Reinstalling fixed this as of now. This related to previous problem?

Thanks in advance.
