Item group not found

I keep getting an error saying “Could not find item group: Products”… Any ideas where to find the source of this message…I’ve looked under ‘Item Group’ and I cant find anything referencing ‘Products’

When does this pop-up occur?

Every 5 minutes regardless of what i am doing in the program. I think i may have POS customers in my queue using this deleted item group and it must be trying to Sync the POS sale but failing as it cant find the Item Group. Any way to delete the customers in my POS Queue using this item group
