Landscape Painting Smooth Bug

Bug Report

Engine Version - Ue5.4
Operating System- Windows
Description of the problem - When using the landscape painting tool, there is a tool for smoothing between layers. When using this smoothing tool, it often breaks. Instead of smoothing the selected layer, it removes that layer.
I have provided a screenshot that shows how the issue appears to be tied to broken landscape tiles. You will see in the screenshot that it has smoothed the 2 dirt layers on either side of the broken tile and removed the selected dirt layer on the broken tile.

The Expected Result - The expectation is that the smoothing tool works on all landscape tiles.
