I also see this on Chrome after installing a new module. I think language strings are getting cached by browser before translation is applied.
To fix it
- Clear browser temporary data
- Close your browser
- Clear flarum cache (php flarum cache:clear from command line)
- Restart your server
- Open the browser
I am not sure all these steps are absolutely necessary, but that's what works for me.
Cheers,
