Quote from starlonYou can restore defaults under the UnitTooltip module and it'll get rid of your extra lines. Or you can delete them individually.
What happened is I made a poor design decision when I localized strings. So now if a translation changes, then you end up with two lines. If I "fix" it, then I'll get a ton of bug reports for sure. If I leave it alone, then I'll end up with the occasional bug report wondering why lines keep doubling. So I have to find another solution somewhere.
Sorry for the issue. I'll figure something out soon. :) But yeah, hit the little button to restore defaults in the UnitTooltip module. I think that should fix it. Let me know if I'm mistaken.
Maybe make a startip for each language? Or in the settings a seperation between the languages so there is a more clear differentation.
