An issue where the shotgun menu does not appear when using rez

Flow Production Tracking

I want to add rez as a field to the shotgrid software entity and configure Nook’s default settings with the rez package.
If you currently leave the tk-nuke field empty, the shotgun menu appears normally.

However, if you add the name of the rez package you want to use in the rez field, the shotgun menu does not appear.
