Hello

I’m trying to export a series of families after cleaning them from junk parameters.  
this is what i came up with:

As you can see there is a warning:

I have searched the forum, seems there used to be “Document.Open Background” before that has the same usage as the one from rhythm, when connected to “familydocument.deleteparameter” no warning is present!

would really appreciate any help
