With a new flow I created, when I change a variable with a flow, it creates a whole new different variable.

In the video I created a flow to enable an alarm boolean, when testing the flow, Homey creates a variable called “False” which becomes true.

You shouldn’t use tags in the flow card set a boolean variable. Type the name of the Tag / variable there.

Using text instead of tags fixed the problem.  
Would be nice if the UI didn’t allow using tags if they don’t work.
