Avatar list is messed up

I created a profile type and set a bunch of avatars plus a default one. I noticed recently that new users were appearing with an avatar of a "grey man with a tie" - not an image I had set anywhere.

I went into the avatars section of the profile on the back end and saw all my images had gone and what was there as as attached screen shot - lots of the same image and even more than one marked as "Default"

I slowly deleted each one (every time I got an error message saying it couldn't be deleted but it did vanish of the screen) and re-added my images and set the one for the default.

I then proceded to copy this profile type ready to make another and was suprised to find in my new profile the avatar images were back to the messed up state. And yes the reason for that was simple, in the original profile type it was also messed up again!

This is not only frustrating (it takes a while to delete each image one by one and then add the news ones so very frustrating when a while later it gets messed up again) but also it is potentially insulting for my users as my website is one that suports LTBTQ and encourages people to move away from binary stereotypes, so when someone signs up, to present them with a "choice" of lots of identical "men in ties" pictures may well put people off from completing the sign up.

I have also just found out that today a couple of users changed their profile image (avatar) and although that was recoded in the stream etc, when I look now at their profiles, it is showing this "man with tie" image instead.

Sorry to but this is urgent and I need a fix for this NOW!!!
