Okay, you're not the only ones who got this situation.
For me, custom is better than official, since there is no possibility to accidentally update OTA, if I'm right.
But if you want your status back to official, try wiping cache from recovery. If that does not help, uninstall Wanam Xposed and then wipe again
If you use SEARCH you might found that You are NOT the only one with the problem you have, and the answer most likely is out there, just search, search and then search again
