Apps on sd card disappear???

Hello guys. I really need to solve this annoying problem.

So here's what's going on. I have app2sd pro. I used it to move all of my movable apps to the internal sd card. It's 11gb and has 1.84 gb free.

So idk how but sd card keeps getting filled. But that's another problem. (if you know how to solve it please tell me. )

The main problem is. All of the apps on sd card somehow decide to disappear from app drawer.

Even when I search for them they don't come up. So I go to app2sd and here's what I find on sd card tab: "no movable applications found from the storage" wth does that mean?

Anyways i decide to restart and all apps come back. But within 1-2 hours all of them disappear again. Help!!!

Thanks!
