Why can I see everyone elses retouched photos?

Every time I go to my history or done it loads everyone elses retouched pics and saves them onto my camera roll....? Unfortunately Im not looking to have random nudes saved on my phone so either fix this problem or Im deleting it because Im sick of deleting other peoples pictures I never saved.
