Why is Niagara Distance Field Sampling Different from UE4 to UE5 (Content Example Asset)?

Hello, I’m seeing a discrepancy of the Distance Field Traversal example that lives in the Niagara_Advanced_Particles map of the Content Example project. The bugs are crawling on the bottom faces of the floor instead of the top faces in UE5. I’ve tried this in both 5.1 and 5.5 and the results are the same.
Anyone have any idea what might be going on?

UE5:
