nothing of what you have mentioned makes any complete sense, are you a fast ring insider? the builds you have mentioned are none that are available to windows fast ring insiders, the os build is 14951.1000.

Go into settings>system>about and give us the correct os build that you are on.

Sorry. The build is 14946

under windows insider , un-register from the program then soft reset your device once and then re register as fast ring insider. do update here and quote me after performing the above steps.

Longer steps. Ok thanks for suggestion.
