Thanks man , so do u have any suggestions ? And any idea why I'm getting these issues ??

Never tick the re-partition option, it can brick your phone.
For your issues I would first recommend a factory reset from inside rom - settings, accounts. This will format internal sd card so backup your data to external sd.
If still the same then download the full GML2 rom from sammobile, check md5 then flash using odin. Follow the instructions in the official rom thread (general forum) exactly.
In each case test before you restore/install any apps or mods.
