User Dictionary Import error

[MerlinMama]

When I try to use the import word, it always gives me an error. Once I close and reopen, the words ARE there, but it always gives me that error message. Just wanted to point that out.

I have tried both entering words manually in the box and pasting it using the Paste from Clipboard button. Both give the same error.

Initial Error Box: AttributeError:'NoneType' object has no attribute 'langcode'

I'm noticing this today, because I'm splitting my user dictionaries into categories, so copy from one to add to another. This happens each time.
