Did the save action for the Event model change?

We recently upgraded to Brooklyn 9.5.10.  Since the upgrade my users are experiencing an error when trying to save a trip report page.  

The error says: “You do not have permission to update the value of this field: Account ID”.  

I’ve track the problem to the Salesforce Event model and the relatedto field.  The save action is trying to overwrite the account id in the relatedto field. In our older version of Skuid, before Brooklyn we didn’t have this problem.  Can someone shed some light on what has changed in this last release and why we are now seeing these error messages?  Nothing in the configuration of the models or the actions has changed on our end. 

What did you upgrade from?

Skuid version 6.8.7 to Brooklyn 9.5.10.
