Good to know you found a solution, Dan. I only recommended ensuring that your fieldtype and modules were up to date because, believe it or not, we do see folks copy back into their freshly updated system folder outdated modules. When that happens, it can have really unexpected behavior. So one of the first steps we take in troubleshooting is to make sure we’re running the most recent versions of the fieldtype and module. Anyway, that’s the reason I recommended what I did.
I’ll leave this thread open so we can hear back from Oliver.
