Project not found when open any rust file, Cargo.toml exists in parent directory but is not found

[JohnBasrai]

Whenever I open a rust source file a window pops up on the bottom of the frame that says
XYZ.rs is not part of any project.

If I select 'i', it assumes the top of the git repo is the project dir, but it has passed up a directory with a Cargo.toml in it before getting to the top of the repo. I do not have a Cargo.toml file at the top of the repo since the project has two executables each with its own Cargo.toml.

This is the truncated tree of the repo.
