Trouble With Blender 2.8 Cloth

I am having trouble with the cloth sim in Blender 2.8 Beta. I am making curtains and when I enable the cloth sim on the plane it shifts downwards, and I am unable to move the plane back up. The location,rotation, and scale of the plane is applied and I’ve tried making new planes and the exact same thing happens. Any ideas what could be causing this. Below is before / after enabling cloth sim.

its making me cry :,(

Ehm, what is causing the the curtain to shift? Just the fact that the cloth sim is enabled, or you mean that running the sim makes the curtain fall? A blend file would help.
