It recalibrated because Ben didn't use it for 5 years, everything was so outdated it wouldn't work properly anymore. The reason why Ben lost his old aliens was to avoid glitches because his old unlocked aliens were in the old watch, the data wasn't up-to-date and could damage Ben's transformations. Giving him a new playlist makes it work better, while the old aliens are locked due to the rebooting. Ben needs Azmuth allowing him to use his old aliens, but as we see, Ben can do just fine even with new aliens.
