I can't seem to find them for individual games, just the overall medals amassed.

Did I miss something, or was there no way to see what the medals you earn in a Crucible match were?

You can see what the medals are on your Legend > Crucible page at the very bottom, but sadly it won't give you a rundown of which medals you earned in which match.

Also for some reason some of the medals are not on the list. For example Heating Up isn't on there. Which is being thrown around (even by me for awhile) that it is when you get a certain number of kills, but the more I play I'm pretty sure it's amassing a certain number of points since I've gotten it for capturing a capture point.
