Are there really Unsupported Minima?

I’m printing a hollowed out 3d sculpt at about 5mm thick.0

No matter how dense I make the supports or increase the point size, I get an Unsupported Minima warning but nothing shows up red on the model. (I have Show Minima turned on.) Are there really Unsupported Minima?

It’s a somewhat detailed sculpt, so maybe some of the details are confusing Preform?

NM, answered my own question. You can “hide” the supports by clicking Edit… made it easier to see where the one red bit was.
