Fileupload multiple image in a tab not displaying images properly

Hello,
I am using multiple tables with Fileupload for multiple images and it works good but when I go to edit page and click on that tab, the previews look like the screenshot I have attached.
When I click on any of the images they all appear just fine, I don't understand why they are not displaying when the tab loads the first time?
Please help me fix this issue.
Thank you so much.
