Some mistakes in ubiquity slideshow

Hello, not sure where to post this, but I was translating ubiquity-slideshow-ubuntu package & slideshow-oem-config-ubuntu-mate and found some mistakes.

In 24.English there is one g to much in stratgegy
.... We've also selected the very best open source games and stocked the Software Boutique with platformers, shoot 'em ups, racers, flight simulators, puzzlers, turn based stratgegy and first person shooters.

And in 28. I think there is dot missing at the end.
which supports many popular streaming services, in the Software Boutique

Also wondering why there is no translation at the beginning of installation even if everything including this is already translated.

Does this happen in any other language?
