Lake water plugin not working

I can’t get water body lake to show up OR deform in anything but a new terrain in ue5, not in 4.27 or .26, on further review, the ‘body of water’ is floating wwwwway up high above the spline, here in .27, what on earth is going on here :)))

Pls see picture Tried moving lake to splines, no luck no change. Out of ideas. NO wonder lake isn’t deforming terrain, what a mess.

thx
