According to the change log, you have not uploaded anything. Do you have the correct format, i.e. jpeg? Does the poster have the correct proportions (1:1.5 (2:3)) and is it at least 500x750px in size, or no larger than 2000x3000px?

My covers are always in 1000x1500px format, what always happens is this problem in several collections in the PT language: you send the cover or background and it gives the notice that it was sent successfully but it does not appear on the website, and as this refers to some problem, I will always report it.

Okay, weird. Is there any error message or something similar popping up?

Not only does the message appear in the sending window that it was sent successfully and it does not appear on the website. I try several submissions before reporting any problem. Next time I will take a print of my screen.

Can you share a poster that doesn't correctly upload here (via Imagebam or something like that), so I can try if it works for me?

I did a test now when I saved the file in Photoshop it was generating some characters in the file name I removed some and made the name simpler and now it was the first upload in the Blade Runner collection.

Okay yeah, that could be the problem
