It’s a false positive, as well as an incorrect suggested fix. The case is weird though, as in one of the sources the shape becomes a flat line (it interpolates to an invisible shape).

Yes, Nabla is one of the trickier ones. My apologies.

No problem! It is very cool to see how sophisticated the tool is, and I’m impressed with how accurate it generally is.
