Spline Mesh and Nanite not working...

Hello,
does anyone experience the same issues with nanite and spline mesh?

I have this issues with all meshes I use.
Without nanite this bug doesn´t show up.

I tried a lot of stuff but didn´t find what configuration i have to use to prevent this bug.

Nanite disabled. Or close Distance with Nanite enabled.

Nanite enabled with far distance.
