Thank you...:-)
On next few days (we bet on 16th) that 14393 build (or next) will become the only official, and 10586 (threshold) will be removed
Simply exit Insider for now using the stop preview builds button, and let your lumia updating and syncin all its core apps to newer version, it will take a couple of days.
For a general purpose answer,
you cannot downgrade a phone like a notebook, sorry...
