transition pack preset

Hello,
I've download transition pack preset and import it on my preset effect folder and when I try to apply transition in the same way that the tutorial, that doesn't work correctly (either it make a kind of mosaic, either it just doesn't work). I have the same problem with an anterior transition pack preset so I conclude that the problem is not with the transition pack preset but whith a new premiere pro version or I don't know...

Thanks for your help,
Eloi Rouger
