The issue status had to be on Needs review.

Tested the the MR changes, no phpcs issues found.
Moving it to RTBC.

Was this tested locally before moving it to RTBC ?

I tested it locally and found not issues, I also could access the admin settings and add new forms to the list and found no issues, I'll move it to "Fixed" and approve the MR

Automatically closed - issue fixed for 2 weeks with no activity.
