How can i solve these foliage shadows popping in

Hello i am having these weird pop in shadows on my foliage and it looks really bad, even if i disable cast shadows under foliage options it does not fix the problem i have this short video showcasing the problem

If i disable dynamic shadows in my directional light the shadows dissapears but i want dynamic shadows for everything else that isnt my foliage.

I don’t have enough experience to figure this out myself as i just started with unreal.

Here is a link to the video showcasing the problem: weird shadows on grass - YouTube
