Document Text Bug in V7?

Is this a bug, or are v6 layouts designed to not carry over correctly to v7?

Example of v6 imported layout doc text on top line, so I added the v7 document text version below to see what’s changed.

Hi Jonathan -

The python function parser in Rhino 7 is new and requires correct casing of the functions.
That said, the intention was not to break Rhino 6 files and we have already added some extra checking to try to get those into Rhino 7 as one would expect. Clearly there’s more going on here.
I’ve put this on the list as RH-61735 for a developer to look into.

Thanks Wim. I didn’t try every document text type but just those two.
