Image background layer missing in layers panel

[JeanJean123]

I opened an image and added adjutment layers. The image is still showing in the workspace, but the image layer isn't showing in the layers panel. The adjustment layers are showing, but not the image layer. I looked in history and I see that I unknowingly created a group, but I don't see the group in the layers panel, so it's probably in that invisible group layer. I merged the layers just to see what would happen and it said there's no image, so I undid the merge. How do I get the image layer or even the group layer that I assume exists but I don't see, to show up again?

Could you please post a screen shot of your Layers panel?

Go to the top of your layers panel and make sure you have not turned on a filter.

Please post a snashot of the layer panel so we can figure out the issue

Thanks everyone! I didn't get back on PS to open the project until just now. The background image layer is showing up now without my doing anything. It resolved itself. I will definitely be watching to see if any filters are turned on at the top of the layers panel though. That might have been the issue.
