[I’m Avast! Fans from China.So,my English is not very good.Please pardon me as my English isn't very good.

When I use Avast! Beta Version(17.1.2283),I met some problem.
Avast! Language sometimes change automatically.Sometimes shown as traditional Chinese + English, and sometimes it will be normal to show my choice of simplified Chinese(as shown in the figure).When the language is not simplified Chinese, close the window and re-open it will resume.
Hope that the official found this problem and repair as soon as possible.
