It used to. I think I’ve cleaned most of those up. I don’t know of any others.

I had to preload the custom fields due to errors if the data was blank. It was tricky to debug at first because I had existing data so I couldn’t replicate the errors reported. Then someone mentioned this process in Babble. Once I implemented it, the errors were gone. I never looked into it further than that.
