SwiftKey 2.7.8 kills physical keyboard layout settings on iOS!

Hi, the update 2.7.8 is blocking the layout for physical connected keyboards on iOS. I have a german keyboard which only uses the english layout and I cannot change it in the system settings. with prior versions the „Automatic“ setting works great, iOS recognises the correct Layout of my original Apple Smart Keyboard Folio on my iPad Pro. If I remove the SwiftKey keyboard in the iOS settings or change my virtual keyboard to toe original Apple keyboard before I use my physical keyboard all is working normal and I can use my german keyboard with the correct layout. Any ideas how to solve this? Thanks!
