Question [Q] No internal SD Card in Archidroid v 1.7.18 as Second ROM

Hello everyone

I recently flashed my sgs 3 to have dual boot, using devil recovery and Googy kernel v2.3.2
First ROM is cm-11-20140815-NIGHTLY, second is Archdroid 1.7.18
While first ROM just runs fine, the second ROM worked also but with a strange issue: It is showing root and external sd card but no internal sd (while using file explorers), seems like it is not mounted or something like that, even xposed installer and other programs that require inernal sd card are not working properly.

Is there anything I can do or this is definetly an incompatibility between ROM and Dual boot ?
Actually: Galaxy S III GT-I9300 Titanium Gray (I know that color does'nt mean a lot )
ROM #1: CM11 Nigthly 20140815
ROM #2: Archidroid v 1.7.18 (Looks like not for a long time)

Kernel: Googy-Max2 Kernel 2.3.2

Base Band: XXUGMK6

Looking for a damn working Sammy 4.4.x !!
