Hello, the devs of Detailed Animations have stated they couldn't prevent overlapping animations (running mid-air) with the mod.

Since this is a mod, it has the ability to change animations more freely than a resource pack. Why not disable animations from Entity Model Features, used for many player animations like Fresh Moves and Serious Player Animations, when using a glider? This could fix #67.
I'm sure EMF devs would cooperate for the sake of compatibility with other mods. I'm thinking of a universal signal for "I'm displaying an animation right now, please disable yours" to solve overlaps.
