This is driving me crazy right now too. What I'm trying to do is very simple and I get the same error even trying a work around where I have multiple columns with the same data value, but different variable names. This would save my team loads of time in making concept sheets where we can just edit the info in a google sheet and pass the data through into illustrator but at this point I don't think its possible. This bug really should be addressed as it makes this variable feature pretty impractical in use.
