Hello,
1) Translation files should have the correct name, you missed “s” in the xstore word http://prntscr.com/io0166 I have changed the name and My account is translated http://prntscr.com/io00iu
2) After renaming everything also is ok http://prntscr.com/io02s5
If you need to translate other strings use Loco Translate plugin. It will help you to translate site very easy just in few click via Dashboard http://prntscr.com/io03hy
Regards
