Image Picker already shows an image from different row

I have a table where users upload photos through an image picker, along with some other data.
Every time the upload process is finished, a new blank row is added with that user’s email, so that user can upload another image.
However, at that moment the image picker already displays an image from another row of that table.
Do you know how to fix that, so that the image picker is empty before a user uploads an image?
I’ve somewhere in the forum some solution with an IF column with a placeholder image, but I’d really like to understand why this is happening.
Thank you very much.

Can you provide some screenshots or a video of your app flow? Sounds like something isn’t set up correctly.
