I have the following multi data triggers. The dependency property is also checked that's why I am not posting it here. I have comment to every data triggers enter and exit actions to what they are supposed to do. The second one is working just fine. However I can't get the first one working! Is there any possible way that the data trigger is working but my storyboard gets overridden
