user interface, unable to submit buttons/screenshots

I have two addons under

For a recently submitted one, I can upload(edit) screenshots/buttons.

For one which I submitted in 2021, there is no field

Images [ Edit ]

My old addon, of which new version I submitted today, has a generic icon, and no screenshots, no option to edit/add them.

What can I do? Is the standard procedure to submit an extension as a new addon every time the developer wants to change its icon/screenshots in the description?
