I believe the Relational View feature using a multiColumn dropdown does not update the bound record when selecting a value.
The demo here does not update the value or mark the row as edited:

The documentation sample which has a GIF showing the record changing does not actually do what it shows when you copy the code and test it:

I created a test that is based on the documentation code, but does not actually update the row when changing the value in the drop down.
