Vertex painting doesn't affect certain areas of the mesh Blender 4.5.4

Ok, I’m following the Complete Blender Creator: 3D course and I’m learning sculpting. So far, some things are a bit different in Blender 4.5.4. First of, painting is easier to do in the Vertex Paint workspace (if anyone else is struggling with that). Second, vertex painting seems to not work on areas that were another mesh that were joined in. Here, I created another ocbject for the ears, and then joined that mesh to the head. So they’re only one object now. But vertex painting doesn’t work in that area. In Solid mode, you see the color, but in Material preview you can’t see it anymore. Does anyone have suggestion on how to fix this?

Figured it out! For anyone else who runs into this, it created two material channels when I merged the meshes together. Deleting one so that the entire mesh has the same material for the Vertex Paint did the trick.
