I had screenshotted the pacelines that I had selected in the Selections forum, so I made a few changes:
Under "Paceline Tools", I selected "00 Manual (You select!), rather than letting the computer automatically calculate using the other tools. I also de-selected "Select Pacelines during Race Assembly".
I cleared the cache for the MVR card that I had downloaded (only worked the one race - Race 2). I then went back in and selected my pacelines from before.
BL/BL appears like this:
BL is consistent with my post in the Selections forum.
Rx on the other hand, is different:
In the Selections forum, the Rx looked like this:
I then opened a new race within the MVR card. Then, I re-entered the 2nd race. No change.
