Language problem on the backend

Hello everybody,
I installed the plugin today.
My main language on the website is Korean, but my profile language is set up to English
(because I don’t speak Korean) so normally I am supposed to see everything in English on my dashboard. But the Ultimate member plugin is the only one which is translated to Korean.
Is there anything I can do about it?

For information I use WPML to translate my website in different languages but the problem happens even when WPML is deactivated so I am not sure if it is a compatibility problem…

I have an Astra Pro theme.

Any help would be really appreciated
