Given the following situation:
I have an organization with the internal note "premium"

Now I create a filter rule, trying to access that internal note

The filter action shall set a new SLA

But I just can't get it working. SLA stays old when I create a ticket for a user, which is 100% connected to that organization. (I can see the organization attached to the user, when viewing the new ticket)

I can assure, that setting SLA with the same filter works if I choose as filter criteria the user's name or email address.
I can see the new "due date", and the SLA on the ticket's detail view.
No issues at all here, nice!

But I can neither access organization's or user's internal note for the filter.

Can you confirm this potential bug? Or am I doing something wrong here?
Shall I post that on GitHub?

EDIT:
What I can also confirm: Setting the SLA via a custom form variable is working, too.
But I do not want to rely upon user input in this case. I want to set the SLA myself at the organization, when initially creating the user / when the user signs a contract.

The value above is a custom forms choice field

PS: How can filter rules be debugged? Is there any output one could analyze? They're not logged in debug logging mode.
