if u didn't installed the xposed along with the devbase rom, u could install the "alt version" from wanam xposed with cwm/twrp. don't think u can install it with titanium.
I had the same problem. U have to use the "alt" version of wamam xposed framework 84. It worked for me. hope it helps.
"-alt- verion should be used for some Note4 variants: N910F/G/P and Note Edge N915F/G running Marshmallow TW Roms"
