Cannot fill form in protected docx files

Hello!
I have two protected docx files, which both contains some forms that I should fill. When I open either of them using ONLYOFFICE Desktop Editors, I get a yellow pop up warning me that the document is protected and thus I can only fill forms. The editor, however, does not allow me to do anything, I can’t even fill the form.
Here are the documents: 212.4 KB file on MEGA
I am using the openSUSE Linux distro, the flatpak version of the Desktop Editors (7.3.3).
Any idea what’s going on?
Thanks!

Hello @Tomoms
How exactly did you create these files? It seems that you created .docxf file > enabled Protection with Read-only parameter and then you saved files in .docx format.
Please provide us with details of these files creations.

Hi @Alexandre , I apologize for my hugely late reply. I did not create these files. I have no control on how they are created. I can only say that MS Word is able to write in the forms as expected.

Understood, we are checking the situation.

Thank you very much! Cheers!

Hello @Tomoms, we have released Document Server version 8.2 that includes the fix of the issue with legacy content controls (checkboxes) in one of the provided files. Unfortunately, the second file includes form fields that are not yet supported, there is another bug for that. We will additionally inform you when the second bug is fixed.
