Second form activation entry criterion is not saved

[samsontu]

Describe the bug
When a Form activation has two (presumably >= 2) activation criteria, after clicking "Apply" and "OK", then the 2nd criterion is not save and the form behaves as if there is only one activation criterion

To Reproduce
Steps to reproduce the behavior:

1. Go to Project/Forms and create a Form that has activation criteria 'is a subclass of A' and 'is not a subclass of B' (see first Screenshot).
2. Click on 'Apply' and then 'OK'
3. Observe that the second criterion 'is not a subclass of B' is not being applied
4. Return to the definition of the form, and observe that the second activation criterion is no longer there (see second screenshot)

Expected behavior
The Boolean combination of form entry criteria be saved and applied to determine whether a form is applicable.

Screenshots

After leaving the Form definition page and returning to it, the 2nd form activation criterion is no longer there:
