Distance Fields behaving weirdly in UE5 Preview 2?

I opened one of the projects I was working on in the UE5 EA in the UE5 Preview, and I’ve noticed my materials using distance field nodes seem to be working weirdly now.

Interestingly, the issue only seems to pop up when the nodes are used with either World Position Offset, or with either of the Opacity inputs: I have no idea what’s going on with the former, but the vertices don’t seem to be displacing properly, and with the latter it seems to always return a distance of 0. It’s working fine with Base Color and Emissive though.

Any idea what might be going on?
