"Add/Remove Multiple" Icon Missing for Glide List Fields on New RecordsDescriptionThe "Add/Remove Multiple" icon (used for glide_list fields) does not appear on new records. It only becomes visible after the record is saved.Steps to Reproduce When creating a new record and using a glide_list field (e.g., a reference list to another table), the Add/Remove Multiple button will not display. This can cause confusion, as the icon appears correctly on existing records. Steps to Reproduce Log in to a demo or test instance.Navigate to Incident > Create New.Right-click the form header and select Personalize > Form Layout.Under Create new field, configure the following: Name: TestType: ListTable to reference: Problem [problem] Click Add and then Save to return to the Incident form.Observe that the Test field does not display the Add/Remove Multiple icon.Save the Incident record, then re-open it — the icon will now be visible. Cause This behavior is by design across all ServiceNow versions. When a glide_list field is used on unsaved (new) records, one side of the many-to-many relationship has not yet been defined — the new record does not yet exist in the database. Displaying the Add/Remove Multiple button at this stage would risk creating broken associations or data inconsistencies. Resolution There is no defect. This is expected behavior to ensure data integrity.WorkaroundTo enable the Add/Remove Multiple icon for glide_list fields: Save the record first, so the current record is created and has a valid sys_id.Once saved, the icon will automatically appear. Additional Notes This applies to all list-type fields referencing another table (glide_list).Related many-to-many (m2m) relationships require both sides of the relationship to be defined in the system before manipulation is allowed.Related Problem: PRB607065
