UE4.26 Water Plugin Help


I’m new to Unreal and am currently struggling with the water plugin in 4.26. The lake, river and ocean each work as expected individually but when I try using an ocean with either a river or a lake (or both) in my level they stop affecting the landscape (even though the affects landscape option is still checked true) and all float above my landscape with 90 degree edges. It seems to work in UE5, I’m just not sure what I’m doing wrong in 4.26! Any suggestions would be really appreciated.
