Hi @shaonyuvi
I don't understand what the problem is - Metabase shows the actual ID, when you are using a foreign key display value. If you don't want that, then reference the actual table entity ID instead, when setting up the filter connection to the card.
@shaonyuvi Change the connected Field Filter column in the sidebar. I cannot see what it is connected to. Then you can look in Admin > Data Model > (db) > (table) > (field) to see more about that field.
