Insert images in order But When Modify... images messy

[basnek]

Hi,
Why is this happening to me?
When I enter a new post with images that I post in an orderly fashion, everything is recorded well. But when editing the post to alter part of the content ... The images appear all messy. The weirdest thing is that the json stored in the database is correctly ordered.
Sorry my bad english
I home the image helpt to see de behaviour
Best Regards

Step 1: Insert

Step 2: Modify
