I’m having trouble getting the lookup filter to pull the correct options when using the “in” condition in conjunction with another model’s records.  

For example, On a page I have a model for ObjectA, which is above another model for ObjectB. Somewhere on my page I have listed out the records in my model for ObjectA, so I know that there are multiple records listed.  I have a popup with a field editor for ObjectB on it.  On this field editor there is a lookup field to a record from ObjectA, rendered as a dropdown list.  On the filter for this field I have configured that the ID of the dropdown for ObjectA should be IN the “field from another model” source Model ObjectA, source field Id. When I do this, all the records in the database show up in the dropdown filter, not just the ones that are actually listed in ObjectA model.  If I change the IN to = then just the first record from the ObjectA model is accessible in the lookup field’s dropdown (this would be the expected result, although not what I need).  

This page was working as expected before my system was updated to 9.3 (previously on 8.15.8) 

Is there another way around this? Or is this a known bug with a fix that is in the roadmap?

Thanks
Susan
