Facebook and Accounts issue.

So, I bought a Sprint Note 5. First day of owning it, I rooted and flashed one of the deoxed roms listed on the site (sorry, can't recall which at the moment). Everything had been perfect with exception of one tiny thing. My contacts don't have photos assigned to them. I started to investigate my settings as to why Facebook hadn't syncd with them and noticed some users have an extra setting in their Facebook app than others. Mainly the sync contacts option. So, I went on over to my accounts tab under settings and noticed my Facebook account wasnt listed. When I clicked add account then clicked on Facebook, one of two things would happen. A. If I didn't have Facebook opened already, the screen would act as of it were about to load sobering then kick me back to the original accounts page under the note 5s system settings. Or, B. It would open my prelaunched facebook app. I think this maybe part of my problem, as it won't allow me to add my account and this sync my contacts with it. I'm not sure if this is due to removed features from the rom, a modified accounts.apk [if one exists. Was only able to locate the account and sigs for note 2] or possibly some missing services that were removed. What I was hoping for was if the accounts portion is actually an apk, if someone could attach a copy of it. Or, if someone knows why this would be happening, to fill me in. Thanks in advance.
