[Question] smg900s android contacts app issue

[benzione]

hi,
i have problem with stock android contacts app i have HDC galaxy S5
(smg900s) with this rom:
KOT49H.G900SKSU1AND3 – S105_XLSF - SM-G900S_V16 – G900SKSU1AND3
it shows android 4.4.2 but i think it's actually 4.2.2 the problem is that when i switch language to arabic or hebrew or any other right to left language the index bar in the contacts app is moved to the right side of the screen hiding the contacts names, furthermore the letters on the index bar
isn't turning to arabic hebrew or with the language of the system that i've choosing but it stays in english letters and therefore it's not usable,
i think that the origin of the problem is in the chinese modification of the android version that the manufacturer have been made affecting and causing
this kind of malfunction in other languages
anyone can help to solve that issue?
thanks a lot,
ben
