Insider Release Preview not showing on my PC as an option?

[scottwallace5]

When I try to switch it only gives me the option of Fast and Slow. Currently on Slow build 14986

Maybe someone can correct me if I am wrong, but I think that's because "14986-Slow" build is a newer build than the current pre-release build. You can't go backwards without wiping the computer and reenrolling to the pre-release version.

The only way you could go back to pre-release without wiping is if the current stable build goes to 14986.
