Issues with crescendo hairpins that carry past their measures?

I am not sure why this is happening, but the crescendo hairpins that I've added to my score seemingly repeat their effects for the rest of the piece. I've never had this happen before, and I would really hate to have to redo my work. Removing the dynamic marking at the end of the crescendo does fix the issue but I've literally never had to do that before to get it to work. Does anyone have any ideas on what might be happening and how I could fix this? Here is a video to demonstrate what I'm describing: https://imgur.com/a/D0KFoeA
