Images are not being uploaded

I was using a list view of images to show all the images uploaded by the user before saving this in the base. It was working pretty fine.

Now, the app is uploading, it shows the snack bar that the images were uploaded successfully. However, they are not appearing in the list view anymore. Has something changed to avoid the list view showing the images in the app?

I put some screenshots below showing the settings defined. Did I set anything incorrectly?

Thanks in advance for any help.
