Power Editing Language Results in Stats/Meme Errors

This is a bug that came in to us via email and I confirmed.

1. Go to Your Books
2. Choose Power Edit-->Language
3. Select titles and change Primary Language to English
4. Go to Stats/Memes-->Under "Language" changed titles now show up as Unassigned, unofficial or deprecated language code (xxx)

Additional details: When the catalog view includes Languages, these changes result in that field being populated with "English," (the comma is there). Double clicking and using the drop-down menu and selecting English again eliminates the comma. Now they do not register as Unassigned, unofficial or deprecated language code (xxx), but, they also don't get added to the English category.

May be related to this bug, though in that case the language code was Unassigned, unofficial or deprecated language code (Eng)

Long-standing bug, see https://www.librarything.com/topic/289075

Earliest report I can find (October, 2010) that correctly traces it to the Power Edit:

https://www.librarything.com/topic/99519#2319402

And I posted about it https://www.librarything.com/topic/330333 a few weeks ago with an explanation of the Secondary language actually being the culprit and what exactly needs fixing ("no change" should actually do "no change").

But apparently stuff only reads mail these days... :)

>4 AnnieMod: There's also this bug from 2016, discussing something similar I think?

>5 gilroy:

You can change the secondary language now (that's how I fixed the few hundred books that got messed up before I realize what it was doing), it just changes it to nonsense if you use "no change" :)

But starting from https://www.librarything.com/topic/216919#5450753 they indeed hit the same "no change" problem.
