@cmallonee, @paul-griffith,  
Have you reproduce this issue on your side ?  
The error message in the vision client is filled with those error…  
I have this issue for every dropdown with enabled binded to a checkbox.

I’ve opened an internal ticket to track the issue. Actually, Paul did a couple of days ago and didn’t link this thread. Mine was closed as a duplicate of his.
