Summary

I have an RR Map, edit the track and test, all is good until…
I edited the track, test it in the game, and now I have the new track and the old track in the game but not in UEFN
I click the "rebuild track’ button thinking that will fix it and there is no change.

Is anyone else having this issue?
Is it a known Issue?

It feels like there is a cache not being removed somewhere.

Expected Result
