Rendering glitch when using Text frames

[hla]

PlanMaker 2021 (rev S1030.0201) 64bit

1. File -> New -> Normal template.
2. Switch to object mode.
3. Insert text frame
4. Inserted one more text frame and added an elbow
connector with an arrow between them. (Pic001.png)

5. Go to print preview. Return to sheet.
If everything is alright graphically, move one
of the frames a bit, and then go to print preview
again and return to the sheet - the border of the
text frame is rendered incorrectly. (Pic005.png shows the issue).

Pic006.png shows how it looks when I try to move the "frame 2":
I clicked on the black-bordered area (where I put the red X on the screenshot)
and Planmaker renders the "movement blue dotted box" where the actual
Frame 2 object is -> underneath the "object" I clicked.

(When you save the file or resize the shape, the object
and its "ghost" reassemble - seems you're missing a "refresh UI()" in the code
after print preview window closes , nothing more...)

Thanks for reporting this problem. I was able to reproduce it and forwarded the details to our developers team.
