I don’t think the issue comes from us.

I reproduce this behavior only if the extension has just been installed (when I test a new build), and only for panels where labels are translated, and only for the first panel I open.

For example, if I open at first the conjugation tool [CTRL+SHIFT+F8] (where labels are not translated), everything is fine. Then, if I open the main panel, it’s still OK.

So for some reason, labels are not translated in the first panel you open.

Seems to happen only in Nightly (has been there for a long time).
