Banding/Stretching on Height Map When Using Shape Splatter

Hello, I am a beginner to Substance Designer and I have been trying to create a bismuth material using the Shape Splatter node. I've used this node before in beginner tutorials, and it always seems that when I use it, I get banding/stretching along the outsides of the shapes. I have seen similar posts online with similar issues, but the solutions have not worked for me. I've changed my material size from 2048 to 4096 (which helped some but not much), checked the bit depth and size of the nodes, changed the height scale, and increased the tesselation factor to max, none of which have gotten rid of the banding. Does anybody have any suggestions? I feel like I could be going about this incorrectly, or I'm glancing over a solution.

I've attached two images and my file if anyone is willing to look. Thank you!
