Change language bug

[L.A.Bachevskij]

Hi!
I installed QS when my system language was still my local language,
now I changed it to english, but the applications in the catalog have
still the old name, which is a little confusing. I'd like to know if
there is a way to change, possibly fairly automatically, these names,
without uninstalling and reinstalling QS.
Thank you in advance,
