Hi
@maggie2
I found the root cause of your issue and it is because your image has partial transparency over the entire image.
Here come the details.
In the blending options, here are the selected choices for your image. The important one (which is also the default) is that Transparency Shapes Layer. It means the transparency determines where the boundary of your image exists.
Here is how I found out you have parital transparency over the entire image (tircky yet I use this all the time)
With the Layer Selected, I use the Layer > Layer Mask > From Transparency which pulls the transparency out to a Layer Mask and leaves the image fully opaque:
To make the Layer Mask visible, just hold down the Option Key and click on the Layer Mask (use Alt key on PCs)
The I just use the command Image > Adjsutments > Levels which brings up a Historgram (don't change any settings). You will see that if the image was fully opaque the histogram would have all the pixels in the futhest right postion of 255. In your case all the pixels are less than 255 meaning all the pixels are partially transparent:
This is what throughs the money wrench into the Layer Styles.
If I just turn off the Layer Mask with the inner glow set it shows up:
If I turn the Layer Mask back on, the problem comes back.
I don't know if you need that transparency or not in the image. If you do, here is a way to get around it. Include Layera below that you need that make the composite image fuly opaque, make it into a group, then apply the Layer Style at the gorup Layer
Hope this helps
