Strange error uploading screenshots to iTunes Connect

I am trying to upload new screenshots to my game's page on iTunes Connect, but when I do that, I get an error that doesn't have anything to do with reality and/or common sense. Basically, I upload a bunch of iPhone screenshots with correct resolutions, sizes, etc. and get an error saying that I didn't. I am beginning te feel like I am doing something wrong, even though I am pretty sure I am not.

The error goes like this: "Your binary indicates support for iPhone/iPod touch. You must provide an iPhone/iPod touch screenshot." Again, as you can see on the screenshot below, I have indeed uploaded those screenshots. The binary is correct and is targeted at iPhone/iPod Touch and iPad.

I have tried both Chrome and Safari, all to no avail. I have left a ticket to Apple's support, but that can sometimes take days, and I don't have that kind of time, as the approval process is lengthy enough without this.
