Calculator and Alarms Apps Missing

[TechmeIN64]

I am using the Window 10 Tech Preview on an AT&T Lumia 635. Since updating, the new Calculator and Alarms apps have disappeared. Is there anything I can do to get them?

reset??

I noticed they are both uninstallable.
Thought that was weird because I'm not sure how one would get them back without a hard reset.
