Collabora Code editor saying all words misspelled - wrong language?

I just got Collabora set up and realized I would need access to the coolwsd.xml file. So I added a volume on the container to access this. After having to change permissions on the folder/files, Collabora started. But now when I open one of the documents that comes with Nextcloud, it says all words are misspelled until I right-click a word and Set language for selection.
The strange thing is I don’t think it was like this before setting up the volume. I copied all the files from the container to the mapped host folder ahead of time, so it should be the exact same coolwsd.xml file as what is in the container. Not sure why the language setting is off.
Any idea how I fix this?
Thanks!

EDIT: So maybe I found the solution" In the editor there is a language setting for the document. Maybe I just missed that it was like this before the config change to Collabora.
Are there any language settings in Collabora I need to set?
