Two languages have the same label on Kagi Translate. I found this by having 'Dutch' as a UI language, and opening the selector.
I expect there to be a differentiation between the two. I think one of them is the one in Belgium Limburg and the other one in Dutch Limburg, but I'm not sure about this. If that's the case 'Limburgs (Belgiƫ)' and 'Limburgs (Nederland)' would be good labels.
