Default Arrow ROM GT-i9505

Hi I can't locate where I can ask questions for this ROM so I'm making this thread. Hope that doesn't violate any rules.

Okay so bluntly, here' my problem with the ROM

I have issues with restoring 20% of the apps, I'm using Titanium Backup Pro for this, and Kies doesn't recognize it so I can't even restore my apps from Kies that I backed up.

But the speed and battery usage perfectly does its work as intended.

Any thoughts about this so I can recover my missing apps and can use it with Kies? Or clarifications?
