On lists, there are some options listed in the "Actions on selected rows" dropdown menu that are not linked to UI Actions. There could be new actions created on this dropdown list by installing plugins. For example, installing the 'Security Response Incident' plugin creates new actions (which are macros) on this dropdown list with labels like "SN_SI_secondary"
In case these are new actions that attach tags to records on the list, you can remove these actions by:
- Navigate to label.list
- Filter by Name contains 'SN_SI'
- Set Active = false the resulting rows
