Hello John,
This means that you are using a multivalued property to specify the group manager. Currently, there is no way to remove the button, however you can workaround the issue using one of the following 2 methods:
- You can modify your script to always assign the 1st entry as the group manager, and ignore all the other entries specified by users. In this case, you'll need to slightly modify your script. If necessary, you can also add a small notification to users saying that the rest of the entries will be ignored.
- You can create a Business Rule triggered before creating the groups that will check how many values are specified. If there is more than 1 entry, the Business Rule will cancel the operation.
If you need, we can help you implementing any of these options.
