Wish List Keeps Emptying

For some reason I'll add a bunch of stuff to my EA App Wish List, then the app will update or something, then the the list is empty again. Just what is that about?

After the update today 20th of April there were no items as the 1st image shows. Then I added them all again. And now they're there. But, the next sale, update, or whatever, they'll likely disappear again. Just what is going on?
