Clone tool doing strange thing

[Llyswen]

I am trying to clone the track of the ISS, but just get the blue line. I am Option-clicking to select the source. This is a 40-image stack done in StarStaX. I am on a MacBook Pro, running OS 13.3.1 (Ventura)

I have done this before, so I am stumped

From the Layers panel, it seems you may be cloning onto a new, empty pixel layer. But you have the Clone Brush Tool set to sample from the Current Layer, rather than Current Layer and Below.

Thank you, I will try that.
