FBX animation runs to fast in class blueprint

I’m making a class blueprint for an elevator doors.
The doors were made, and animated in blender, and have four animations: the open and closed idle anims, and two for opening and closing.
When I open the model in persona the moving animations work perfectly.
The problem occurs when I try to make it work with blueprints(class).
The idea is simple. On spawn it waits x seconds, then plays the opening sound and the opening animation. When a player leaves the elevator (used box trigger) the doors close after a 2 second delay. In practice the first animation works good, but the second seems to play extremely fast (doors close within 1/10 of a second).

Here is the blueprint:

Any help would be strongly appreciated.
