Load more button appears in the popup window for replacing the feature image, even when there is only one image available.

Steps to reproduce the issue:

1. Go to the post editor in WordPress.
2. Locate the section where you can edit the feature image for the post.
3. Click on the "Replace" button to select a new image.
4. The popup window will open, showing the available images.

Despite there being only one image in the selection, the "Load More" button is present in the popup window.
