Custom Column Layouts:Monitor-layout dependent? Stored where

I've always had issues with Custom Column Layouts disappearing on me but now that I'm on a laptop, so use Resolve in a variety of setups (lid closed and dual external monitor, lid open + one monitor, or laptop display only), I've realized that my Custom Column Layouts appear to only appear on the monitor layout they were created in!
Here's my custom layouts in one setup…
And my layouts in another!
Uh, wha??
And so the question related to that is… where are these layouts stored? I've lost them before, and I'd love to back them up, and maybe even figure out how to get them to load in multiple layouts.
