The special character in the Nürburgring seem to bug the multi replay incrementation, subsequent launches overwrite the previous file, it's stuck at number 1. Someone renamed it in the GDB and it worked. https://forum.studio-397.com/index.php?threads/nürburgring-2018-is-now-available.64155/page-10#post-1005212
You can also change in the player json to record all replays instead of amassing the 3 sessions into a single file.
I imagine that will just result in those 3 files being overwritten each time, instead of the 1. It's not a fix.
