If there are no maintenance records or transactions using the lowercase state abbreviations, then running Data Verify will cleanup the unused values.

Please reference the following articles for more details on Data Verify:

Note, the unused states will not be listed as an actual data error and simply will be removed automatically behind the scenes.

I ran the Data Verification & only had "contact" errors. I looked at the list of states & all the errors are still there. I have checked all contacts, customers, vendors & none are using the states with the small case letters.

Any other suggestions?

You may want to check your transactions. If the states are used on transactions such as Invoices, Purchases, Receipts, etc, Data Verify will not remove them.

I have checked everything & there are no transactions, customers, etc that are using one of those few states that are in lower case. They have the upper case version of those states. All the customers/vendors were checked for active & inactive ones as well.
