Subform Bug- Adding New Entries in a Lookup Field

Subform Bug- Adding New Entries in a Lookup Field

Hello, I need assistance with a problem relating to the subform. When I add a lookup field in the subform while checking the choice to "Allow new entries," I have to refresh the page whenever I add new entries into the database for it to show up in the list. The problem only occurs in a subform, but not if you do it in the actual form. This would not be user-friendly for our suppliers, as a result. Any assistance would be greatly appreciated.
Regards,
Mohammed Alhaj
