IF statement output value is being held but needs to reset to 0

Hello,

I have implemented different states in my Simulink model and put the 'state when action is resumed' parameter on reset. But I want it to reset to 0. The IF state is true if the tank level is below 20% and as you can see in the figures at around t=700 the tank level gets above 20% and the state stops operating, but the state still retains the last value. I've read that you can reset that to 0 with the state parameter on reset but that does not work for me.
