Grass on landscape Component was messed up when painting blend mask if this component has LODBias>0

• Create a simple landscape
• Create a landscape material with two layers as well as grass node and sample one layer
• Create a Grasstype and assign it to the material
• Assign the landscape material to the landscape and paint the blend mask, see grass is also spreading around on the specific layer
• Select one Landscape Component and set LODBias to 1 or more
• Paint the blend mask on  this component again you will see those grass positions on the component are just messed up

Expectation: Paint blend mask on a LODbias >0 Component doesn't messed up the grass on it.
