Very valid bug information you provided here! Thank you very much!!!
Already noted and will be fixed very soon.

We want to make in the future a small gif animated image that will show how exactly to get Active private key from Steemit.com so it will be super easy to do. Also the QR reader helps a lot, but needs instructions, too. Because on Steemit you firstly have to press on the QR for it to show you password.
