How do I change the case of a column in Config Manager?

Hello,

How can I change the case of a column in a table in Configuration Manager?

For reason I do not know all my columns for a table 'EMPLOYEES' are uppercase except for one 'Department' and the data for this column is not applying when I check in a document.

I thought I had fixed the issue last week, I changed the case for the column in configuration manager and the data applied when I check in a document but the case has changed back.

Here is what I tried last week:

1. Edit Column
2. Change the case from Department to DEPARTMENT
