Question: Converting math to text but still executing

I have a student who has a problem when closing and opening a Maple file.

It seems as if Maple turns math fields into text, but still execute when using ! or !!!

The dark red part is written in a text field, but Maple still executes

If I try to write in a math field and executes, closes Maple and opens again, this does not happen, so it is not the file that is the problem.  The student is running 2024.2 version.

Can anyone explain the problem and how to solve it.

 

I am unable to add a comment or the file. I have tried several times, without any luck
