Mystery of two identical images being displayed.

When I looked at my work, which has not yet been divided into collections, I saw two images side by side, although I was supposed to have created only one. One of them has a "like" and the other does not, so you can see that two identical images exist.

If a copy was intentionally created by tapping some button, it means that the image was created by either a pop-up that appeared regardless of our intention or by touching a button that was created in the wrong place to be pressed.

So, what to do about these images. If I delete one of them, will the other one disappear as well? Or does it matter if I delete one of the images?

I don't want two of the same image and would like to delete it.

Also, I would like to know why this is happening and how to deal with it so that I don't have to deal with the same situation in the future.
