PLEG trigger not triggering

I have 5 triggers, all evaluating my master bedroom temperature. All of a sudden one of them is not triggering although it should. These are the triggers, and the current temperature according to the master bedroom temperature device is 23.3 degrees. So all of them are in the right state, except for bedroomhot1. So i changed bedroomhot 1 to 19 degrees, still false. Set it to below 25 degrees, still false. No idea why. I notice this at about 22.00, and have changed it a few times (see above) but state is not changing no matter what i set it to. I have reloaded Vera a few times, no change.

The triggers are only evaluated when the temperature sensor actually changes a value.
