Notification and summary of gas used after sanitary hot water usage

I have downloaded the flow, and entered the devices I want to use as triggers, as well as modified the words used in the notifications, but I can’t seem to get the logic cards ‘zet gas.value_started of stopped’ to automatically generate the tags needed for the next logic card (bereken gas.value etc).
I use two triggers: flowrate and drawn electrical power (power and flowrate more than) icw and ‘all’ card to determine when my boiler is used to provide hot sanitary water, and these same cards (power and flowrate less than) to determine when it has stopped. These function as intended (tested with individual timeline notifications), but the logic cards fail to automatically produce a differential value: when I run the flow from the ‘all’ card a notification containing the differential is produced.

Any clue what is stopping the logic cards from being executed?
Edit: It seems I can only use one trigger, so I will have to look for another way of differentiating between sanitary hot water- or heating use of the boiler…

Any tips are appreciated!
