For me, no group is showing as being explicitly joined, no matter what the selected custom user field is showing

The image shows an example of forum user information for a professional level, specifically a "Public Forum User" without two-factor authentication, and indicates that the user is an NZIA Practice member and an NZ registered architect without an employer listed. (Captioned by AI)

The ‘Custom’ groups field remains unpopulated, when it should be showing the group name or names selected via the custom user field

The image shows a user interface with a "Groups" section, displaying options to select the "Automatic" group and show a "trust_level_0" group, along with a "Select..." button and a "Custom" category for further options. (Captioned by AI)
