Stock field in Image Dropdown disappears after saving

[AndreeaCristinaRadacina]

Description

While working on a ticket, I encountered a problem with the stock in the Image Dropdown input disappearing after saving the fields.

Additionally, the stock of the images is not correlated with the product stock unless the order is marked as completed. Meaning that users can make a lot of orders even if the product remains out of stock.
