Getting dismounted when entering combat with monomyth mythic on

I have been getting dismounted when entering combat with monomyth mythic on, but only on my backbar. One of the buffs from the ring is causing a dismount. The same thing happens when if you cast the arcanist ability Arcanist's Domain. If you mount up while its active you will constantly get dismounted when someone rides through the Arcanist's Domain you placed.
