Problem with grass

Hi!
I foud this blueprint called “Advanced cinematic grass blueprint” and decided to try it out, but once i put it up on the landscape, the mesh changed when i pressed “play from here”. In the editing viewport, it is a different mesh, but in the play mode, it is completely different.
Here are a few images for better understanding.

As you can see, the grass in the edit mode is different and the play mode is different.

Please help…
Thanks!
