Weird marks when refraction setting is on

Hi all! Excited to be here, as I’m very new to Nomad Sculpt.
I’m trying to create a wine glass design. But every time I turn on the refraction setting to simulate a glass look, I get these weird marks on my glass surface? I’ve tried voxel remesh and played around with topology settings to see if that would fix it, and as you can see from my wireframe, there’s nothing wrong with my mesh! I’m kind of lost here.


Also, I’m not sure if this is directly attributed to my first problem I just mentioned, but when I go to look at my model in the opaque material, I get these weird color blocking segments made on my wine glass. Please help! Lol
