OK, since the bug was corrected by playing the level yourself, and the replay was made by a different user, I think I know what's causing this.
The record is only displayed at all if the level is "completed" - running someone else's successful replay will do this. But, since the record is by someone else, this part of the code hasn't actually been populated yet. To be honest, I'm surprised it doesn't outright crash the Postview screen!
Anyway, if that's what's causing it, it should be a fairly easy fix.
Another bug I spotted whilst testing this - the replay "R" isn't displayed in the panel when playing replays in Classic Mode. I know what's causing this as well - a previous bug caused the "R" to flicker on and off when rapidly changing RR (this actually happens in NL as well), and the fix to this prevents the "R" from ever being displayed in Classic Mode.
I'll get all this sorted for the next update (2.4.2).
