I just added a record in the far western part of the county. I filled in the first 4 fields and used the reason type "Power Line". Once I close that record and open it all the fields are blank. And you'll see if you open the table there are a lot of records that have no attributes at all. But those attributes were entered in the pops and then disappeared (only the ones that used my newly added domains).
I did just notice that after adding my new test record if I then closed the map, reloaded the layer and started over, now the values show up for that one record.
I think I will recreate the layer from scratch, add the additional domains before creating any records and see if I still get intermittent issues.
