I have a simple list named Source1 with columns I added named Col1, Col2, Col3.
I've created a simple filter query in Get Items using the internal Col1 name _x0043_ol1 which I obtained by going to List Settings, selecting Col1 and grabbing the internal name from the URL. Here is what I'm seeing when I do that.
x/_layouts/15/FldEdit.aspx?List={DCF865F8-956B-46B1-9448-AA8DD35A887B}&Field=_x0043_ol1
In Get Items this is what I am using in the Filter Query. _x0043_ol1 eq 'Kuhn'
'Kuhn' is a value in Source1 Col1 of my list.
When I run the flow I'm getting the following error indicating the column doesn't exist.
Column '_x0043_ol1' does not exist. It may have been deleted by another user.

serviceRequestId: eb7b708b-56fd-4c8a-ae01-45c281b73f4e
When I run the flow using column name Title or Author and searching for values I know are there the flow works fine. The issue is the columns that I created don't work when I use the Internal names.
I am using my free Dev license from MS so could this be an issue with the subscription?
