PagePlus X6: Right mouse menus disappear

I open a PDF.
I right mouse click on the image and I see,
PhotoLab
Cutout Studio
Edit in PhotoPlus
Edit in LogoStudio.
If I select Edit in LogoStudio, it opens, I can make a change or not and then use the Close button to lcose LogoStudio.
If I right mouse click on the same image again, all the menus have disappeared except for Edit in Logostudio.

What is going on, this seems like unexpected behaviour?
