Not working on frontend

Hi,
I haven a problem with showtime image gallery in Joomla 4. I made a showtime custom field. When i edit an article in the backend it works fine.
When I open te same article on the frontend the images ar there, but when I try to edit the fields they don't show up. When I try to upload images on the frontend I get the message "Upload Failed"
Tested this on several Joomla 4 installations

Can you help me?

Sincerely
Hans Blankenstein

Ok Lefteris thank you for your response,
Please send me the development version with the fix, I am building a site for a customer that needs the gallery
Regards

Works fine Lefteris, Thanks.
Can I just use this until the update version is released and then overwrite this with the update version without losing my images and settings?
Regards

Thanks a Lot
