HTC One M7 BlinkFeed home screen issue

Does anyone here know how to change the background image on the HTC One BlinkFeed's home screen? It's the background that is displayed when you swipe to the right of the Blinkfeed and see your apps listed there. Somehow a screenshot I took accidentally of my Facebook app is now the permanent background when I swipe right of the BlinkFeed and tapping and holding down on the screen to bring up the Home screen menu with "home screen wallpaper, Add Apps and widgets, Manage home screen pages" doesn't offer me any way to ditch this image or reset it. Picking a new wallpaper does nothing no matter what I pick. Sorry if the question has been answered before but I didn't see when searching the forums.

Never mind. It seems that switching the background image in the BlinkFeed when swiping right has eventually fixed the issue. Craziest thing because it seemed so persistent no matter how many times I altered the background image.
