Parallel Spike trap altered by item use?

[Zelazem]

So I followed this tutorial on My goal is: if the players have a certain item (once they step in region 1 or whatever the video says) they will be prompted to use the item which would "disable" the trap. Now Ive tried a self switch to a new event page thats just the "empty holes" image. However, the spikes keep moving even when Ive already interacted with the item/event. Is there anyway to get around the parallel trigger of the first event?

Can you show a screenshot of the event pages?
