SNAP Land/sea mask - shoreline extension

I may be misunderstanding this option or using it wrongly but I have a vector layer of the lake I am interested in but wish to extend the shoreline by a couple of pixels to remove possible land/beach overlap etc. I can process the scene with any integer in the shoreline extension box but looking at the result between 0 (for shoreline extension) and any other value the masked pixels remains the same. Am I using this incorrectly or is it not designed for the purpose I am attempting to use it for?
Any information would be greatly appreciated.

Used in SNAP 6.0.5

I’m seeing the same issue. Doesn’t appear that the shorelineExtension parameter is being applied?
