Getting unexpected associated field when using Entity Key as filter

Good day,
I have a simple dashboard set up to fetch claim and services details for hospital visits.
Two of the filters are Entity Key fields, which happen to be Claim ID and Patient ID. When I make a selection on either of these, the dashboard refreshes correctly, but the value shown in the filter becomes the ID I chose PLUS a physician name. I was expecting only the ID to show, and I'm not sure where it's fetching the physician name. AFAIK I did not make any association like this in the Data Model or elsewhere.
Please help.

Hi @chrisKH
The change the "Display Value" in Admin > Data Model > (db) > (table) > (column) :gear:

Hi @flamber ,
I checked the Display Value settings in Admin and they are set to 'Use original value'.
However, I noticed that Claim ID was set to data type Entity Key and then further down the table, physician name was set as Entity Name. After changing to Category then it worked fine.
