@jrmenzon-0 I've found the root cause. I did a wrong assumption that in all languages the titles would appear the same, as they now contain full target language name... in the source language.
Unfortunately this is not consistent, e.g.
in English it appear as "Opera (navegador) – Spanish" for [en],
but in Spanish as "Opera (web browser) (inglés)" for [es]
Currently I just trim the title as from the last occurrence of "–", but because of the above, I should not do that
I need to analyse the best approach. Worst case scenario, I will just keep the titles as they are, without removing language names. That would mean, however, that language codes in brackets will become a bit redundant.
