Default [Q] Lost Apps after kitkat upgrade

Howdy folks,

We just upgraded our 4 Galaxy Note 10.1 (2014) tablets to kitkat. Three worked great but the 4th lost most apps on the homescreen (Maps and Gallery were the only ones left). When I go to Settings and Applications I can see them. I've tried uninstalling and reinstalling them... still not luck in actually finding them. As a last resort I did a factory reset and re-installed the apps. They show up under Settings... but cant find them anywhere on the device to launch them.
Has anyone seen this behavior before?
