Culling low grass details on terrain (detail distance issue for not tall details)

Hello. Need some of your help.

I have the terrain and some grass details on it. My grass is two different slots. One of is 0.1 height and one of is 0.15.

Details Distance sets to 100 units, but this not tall grass is culling upon approximately 25 units. This doesn't happen with 0.5 units grass that you can see on the right side of the image below.

How can I solve this problem?

Because my picture has suffered a lot when this low grass disappears.
