Weird reflections in material preview and eevee

Hi, I’m getting this weird effect with transparent parts and reflections when viewing my model in the material preview and in eevee but in cycles it’s fine. I plan on using cycles for the final render but I want to be able to use the preview material view when setting things up so I can see through the transparent parts.

Is the Material Preview affected by eevee settings even when cycles is the selected render. Is there a setting I’ve messed with that is causing this and is there a way to fix it or is it something you just live with?

Thanks in advance!

Cycles in viewport:


Material Preview:

Reflections are also fuzzy in material preview:

But fine in rendered view (cycles):
