Help Constantly being asked to set default home app

[Kr23]

I had downloaded a third party launcher and selected Always as the default, but every time I exit an app, it constantly posters me to select the default home app. I've tried deleting the cache and force quitting Xperia Home, but that didn't solve the problem. I then deleted the third party launcher, but am still getting asked to choose the default between Xperia Home and Xperia Simple Home. Even when I select Always for the Xperia Home launcher, I still get asked each and every time I exit an app.
