QUSQ-PRO languages translation

Hello,

Under QUSQ-Pro, I have created fr-FR.* translation files in QUSQ-Pro\languages.
I used QUSP-Pro-Child theme.

Beginning of this week, I have updated QUSQ-Pro theme…
Translation files have been deleted.
:-((

I’ve restored them at the same place.
;-))

Nevertheless before the next theme upgrade,
I moved these translation file from QUSQ-Pro\languages to QUSQ-Pro-child\languages
but translations are ignored…
Why???
