Issue: If "Resizable" Layout Strategy contains a block, it will influence the "Overlay" Layout Strategy.
Expected behavior: When using "Overlay" Layout Strategy, it should disregard whatever the "Resizable" Layout Strategy contains.
I'm using a data table to get all the relevant assets.
By default, it creates a yellow UV Block to modify the mesh, which is also seen in the picture. This UV block causes an interference when the Layout is set to Overlay.

It pushes the UVs out of the original packing into other UV quadrants (which is by design when actually using the Resizable block mode, I believe), but this is when Resizable mode interferes with the Overlay mode and causes this sort of results:To get around this, I have to manually remove the yellow block seen in the first picture, before switching to Overlay mode. And it has to be manually removed for every single LOD, of every single skeletal mesh.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-368801 in the post.
