Poster approved but not updated

I submitted a contribution on March 20th (#240320-172746-235000) It was approved but didn't upload on the page, I re-submitted a contrubution update (#240327-015200-637000) hoping it was just an error, it was approved but again didn't update.

I submitted a completely new contribution (#240402-194449-574000) today and it was rejected with reasoning of duplicate..

Can someone please look into this? Why is it approved but not updated?
