Can't modify playbook form

[JohnAngeloE]

Hi SNow Community,

I'm having trouble modifying the playbook form. I can change the title, but I can't seem to edit the description. I even tried recreating it from scratch, but that didn’t work either.

Any assistance would be greatly appreciated!

Here are some screenshots for reference.

Plugin: Social Benefits Playbook
Playbook used: Social Benefits Playbook

Tried modifying other modules' description and it seems to work but when I'm using the Show Disclaimer Case Task as Activity Definition, it doesn't work.

Here's an image for reference.

Tried to edit other modules from the OOB itself and it appears that I can edit it well. It just doesn't work on the module mentioned above.

My suspect is it depends on the Activity Definition but still testing things out on what works and what doesn't.
