Real Work Imputation not working

Hi there,
We have been using projeqtor for almost 10 years but for several weeks two of my project managers have not been able to impute their work.
They are correctly assigned to the tasks of their projects and despite all attempts to modify their permissions it is impossible for them to impute their work.

We have given them the same role as another project manager who does not encounter this problem without success.

I went so far as to give them administrative rights and even then they are not able to impute their work.

We notice this problem on version 9.1 and today we have version 9.1.3.

Thanks for your help.

Hello
They can view, edit, change categories. The changes are well saved. The only dysfunction that we have noticed is the impossibility of being able to impute the work.
As a project manager, they can also create activities, a project etc.
Thanks

Hi there
What I mean is for each assignment it is not possible to imput work as describe in the pic attached.
As I said, they can create, modify project, activities.
Tks.
