Are you playing on the right version for the map? If not then that's probably the issue. However, if you are then have you tried leaving and then returning to the area (not dying)? If you've tried both then I remember someone else had this issue before and, looking back in the thread, Mithey said to run a command once you get into the cooling stations
Edit: Looking back Mithey said it was this command but idk if it changed or not:
/scoreboard players set @a Temperature 37.
