The problem with this tree is that the Sequencers are Dynamic. The Trigger Enter and Trigger Exit conditions are only true for 1 frame. As such, and since the Sequencers are Dynamic, they constantely revaluate the Trigger condition which 1 frame later returns false, thus any actions are canceled prematurely. The “SET BLOCKER” action never gets a change to execute.
You basicaly want the Selector to be Dynamic (if at all) instead of the two Sequencer.
Let me know if that solves your issue.
