Hunspell dictionaries for rare languages not working

I've been working a while on a document with norwegian and some different sami languages. I've added the hunspell dictionaries as instructed here: https://helpx.adobe.com/indesign/kb/add_cs_dictionaries.html. And it worked great for a while, but now the sami hyphenation turns off as I try to edit the sami texts (no updates in the meantime). I've tried to remove the dictionaries and the string elements in the info.plist-files, and adding them again, but nothing seems to work.

The Sami text was set ut with the hyphenation working, and now, the text boxes stays that way, until I do even a small change (like adding punctuation or changing the kerning). Then all the hyphenations in the paragraph I'm changing seems to turn off – although the "hyphenate words"-box is checked. The Sami language doesn't vanish from the language list. But when I change the language to norwegian, the words hyphenate in the norwegian hyphenation rules. Which is not as good.

I've tried to make a new document, hoping it would work then, but it's all the same. I have seen that there are two quite similar info.plist-files in the AdobeHunspellPlugin.bundle-package. I thought it might be better to add the string elements to both of them, but it was all the same, and nothing worked.

Any suggestions to this problem?
