Ipad issues with Bluetooth keyboards and iOS 7

Hello,

I seem to be having a strange issue using my Belkin Keyboard folio for my iPad mini since upgrading to iOS 7. For some reason, my backspace key has starting to work like a delete key (i.e. deleting characters after the cursor, not before) and will only work normally if I hit CTRL. I thought it was an issue with the keyboard that just arose; when I paired it with another iPad that hasn't been upgraded to iOS 7 it seems to be working normally. Has anybody had other strange issues with external keyboards and their iPads since upgrading? I've heard it could be an issue with Bluetooth and the new operating system. As I rely heavily on my keyboard for editing and writing, having a dysfunctional backspace key is fairly annoying.
