Islands Disappearing in 4.26 water body ocean

Hello, I’m new to the forums and was wondering if anyone can help me with this issue that started showing up yesterday night. Currently I’m making an overworld for a game I’m working on and I added a water body ocean to my scene and set the splines around the continent. It worked a few days ago and the islands on the right side of the continent were there. I don’t remember what I did yesterday night but as I was adjusting the splines again, my islands disappeared. In the two images I have this is what the islands looked like before my spline adjustment(I’m using the affect heightmap turned off to show the islands) and after the spline adjustment(affect heightmap checked on). Anyone have an idea of where I went wrong? I feel like its a heightmap related issue but I have no idea how to fix it back before I did my second spline adjustments. I also still want the ocean to affect the heightmap since it creates these really good beaches.
