[HELP NEEDED] My MT6582 phone doesn't list sdcard files in root shell topic

Hello guys,
I have problem with my MediaTek phone, mine is QMobile Noir i7, it's working fine as wine, but the problem is when I access root shell phone doesn't list sdcard0 files, when I exit the root shell to shell mode, shell mode list's sdcard0 files without any problem.
What could be the problem?
I've done nothing to it, except installing CTR recovery and rooting phone through it.

Any help would be appreciated :)
Thank you. :)
