Need Help with ENB Problem

[SuperNixon]

For some reason when I'm in certain areas of the Dawnguard expansion I have weird shadowing. This mainly happens in Volkihar Keep and Darkfall cave. Fort Dawnguard and other areas are unaffected. The only other time this happens is when I approach a word wall and get close to the wall while learning the word. I am currently running Seasons ENB. The rest of my game looks great so normally since I don't play Dawnguard very often I just ignore it. I decided to do a playthrough with Ordinator and Sancrosanct and intend to play a Vampire Lord so that means spending time in Volkihar Keep. I've googled this like crazy and can't seem to find a solution.
