I had this same issue. I sent out two mailers and even though I changed the location, it kepts the old one when it sent out the mailer. And yes I clicked to save my change, yet it still took users to the list for my first mailer.
The first save was tabid 17
the second was tabid 18
yet both went to tab id 17.
The only way I fixed this was to delete the modules from my page and set up up with both lists on the same page. This should be looked into. My post:
