Hello BienzoDefranc, thank you for posting your question. I see you have asked this in another thread so I will answer it here if that is okay.
Addressing your concern:
Your WaterZone asset will need to be resized.
To change this: click on the WaterZone actor in your level and adjust the extents to your liking. I think you are smarter than what you give credit for. Great work so far on researching your concern!
I hope this helps.
