YES. It’s happening for us very frequently – at least 5 times today that I’ve had this happen for me. Not sure what is going on, but we haven’t been able to track it down to any filter or any plugin, thus far. We’ve built a theme with Sage and did have to use a few filters to change where the acf-json folder is loaded, but that shouldn’t cause any issues.
This is definately a bug in the import/sync. I have reported it to Elliot. I tried to figure out how to fix it cuz I was in a bind to get something done but I’m completely baffled why the first field in every layout gets pushed to the end.
