Images don’t disappear immediately after deleting

Hi after the last update for WhatsApp, when I go to the media section of any WhatsApp chats and try to delete images, they don’t disappear after pressing the delete key. However they are actually getting deleted after I’ve closed the chat and and reopened them. I know it’s not a problem with my phone as my other iphone is also having the same problem after the last update
