Items found on undefined layers: Rescue. How to delete?

Layout
1

I’ve got a project that was originally created in Eagle which I’ve now managed to get imported in KiCad (6.0.5)

Schematics and PCB layout all look ok, except whenever I now open the PCB Editor I get a error items found on undefined layers. And get a option to delete or rescue them. I have tried deleting and rescue options which don’t seem to do anything. The PCB opens after clicking delete/rescue but when I close and re-open the PCB I get the same error.

What can I do to delete the rescue layer?

First you should have a look at what sort of items are on that layer, and do something with them if they are of any importance to you.

Does the layer show up in: PCB Editor / File / Board Setup / Board Stackup / Board Editor Layers or in the Appearance Manager on the right side of the screen?

As a last resort, you can open the PCB file in a text editor, search for the name of the layer and delete, rename or move S-Expressing belonging to that part.

The Rescue layer is not showing in the Appearance Manager or in Board Editor Layers

After some more digging I found all the Values in footprint properties was set to Rescue.

I ended up editing the .kicad_pcb file and replacing Rescue with F.Fab which has fixed the problem
