Water plugin Issues

Hello everyone,

I have problems with the water plugin of UE4. I am using 4.26.2.
The problem is the following :





As you can see, my water is really strange (I am talking about the fact that it doesn’t fill correctly).

Here is what happened :

My friend gave me his project where he did a long time ago a quick map to test the water plugin. I have opened this project and open his map and I had problems with water (the same we can see on the previous pictures).

So, I thought that it was due to his project, so I open one of my project in 4.26, create a level, a landscape (enable edit layer), and then I just add a water lake BP, and see that it was still causing trouble. I test it a lot of time with the lake or the ocean, I even disable and enable the plugin, I also tested to move the water bp on the landscape, I verified that the landscape was in 0.0.0, etc… I never find the solution…

Would someone help me ?
Thank you a lot for your help and time !

All the best
