Hi,
Thanks for your queries.
1) You can get the override option in backend
http://prntscr.com/moid2a (make sure you've installed the language )
If your installed language doesn't have any language files then please follow the following instructions.
a) Goto this folder location
/language/en-GB
b) There you'll find these files named
en-GB.com_spsoccer.ini
en-GB.tpl_shaper_soccer.ini
http://prntscr.com/moieyc
c) Then copy those files in your language folder
d) And you are all done to translate.
2) Yes i've also found the issue. Don't worry it's already in our todo list( which is quite long ).
We'll fix this in the next update.
-Best Regards
