How long have you been using this add-on? Is this issue recent and never happened before?

Maybe you can give me a YouTube channel name where you encounter this, to check if I get the same issue on my side.

Do you use any other add-on related to YouTube? There could be a conflict.
You're the first one complaining about this issue.

The best for you to do would be to create an issue in github (https://github.com/YouG-o/YouTube_No_Translation/issues), you will be able to properly explain the issue, add screenshots etc...
