I am trying to couple the Unit Group from BC to Sales to have one Unit Group for all items, But when I tried mapping it the same error is still I am getting. Is it correct Unit Group is the first I need to couple then UoM and Items?

For the Unit Group -Dynamics 365, this are the ones on the list. It created when we save the Items. but I know we should only use one unit group for BC and one unit group for Sales.
I tried coupling the unit group thru the items but when I already couple the one item and get the other item couple error message is the one I'm getting.

I need guidance on how can I create one Sales Unit Group and One BC Unit group. I already tried doing some work around like creating the Unit Group in Sales , but still same error. I can't use one Unit Group for all items. Is there a way creating a Unit Group in BC?
**note: Items were already sync in BC from Sales but on the sync job it is on Skipped field. I'm trying to fix this one to have a successful sync in BC.
Thank you for your help
