Poorly reproduces the layout!

Hello! I ask layouts from the admin account, on the client Windows plays everything but after when I want to ask another layout for some reason does not reproduce but reproduces the old layout is not at the time. I went to the library where all the files are stored! Only after I delete the video with the layout is played another! Always will be?
And the bad thing is that in the library all the layouts are not in their folders, and in a disparate and because of this it is very difficult to find what files belong to other layouts!
