Duplication of images

I have a form where people can chose multiple images from but, when he saves his selection and return to the form to edit. He can still chose the image to chose but, it also create the images to which the user has chosed from the previous save resulting in a duplication of images.

It also lead me to an action button that cannot be used.

Here is screenshot of the duplicate images.

Subtract values from a list - AppSheet Help

Is there a way to prevent appsheet from creating these two images ?

When I save, it creates this long URL:

That’s actually normal behavior, believe it or not. That it’s showing text at all suggests the (Enum) column (base) type is a textual type (e.g., Text), not an image type (Image or Thumbnail).
