Why does this RM Rule not always run?

Hello all, I could use some help here

My wife got up to use the restroom at 5:42am, rule ran, got back in bed at 5:44, rule ran and properly exited.

She got up at 5:58, should have run and exited but didn't appear to, I got up at 6:32 and nothing...

C-3 (don't laugh) on FW

What am I missing?
