Doors are just "Stuck" no matter what-Help please

[jssjr90]

Hi everyone, I came to a little but frustrating problem. I was in the process of making an outdoor level with a creepy manor that you can go inside.

Anyways when I placed the front gate "elevator door" it would not open what so ever, yes it was positioned right. So I tried the mansion door for a test run, again it would not open what so ever, yes the door is unlocked.
I don't get it what is going on with the physics?

I also put some containers "boxes or crates" and when I lifted them it took a second to actually grab them, its like gravity was pulling them down. This is vary strange. This does not happen to my other maps. So how can I fix this door getting stuck problem?
