List of play store apps not showing

I have a new dtek50, and i'm trying to update all the apps but it keep saying searching for new updates and nothing happens...can someone help me? it only shows the library (apps that i´ve installed on the Z10 before), but i want to see the list of all apps.

i just installed the cb app, it's weird, it only shows this app in the tab of "installed apps". isn't supposed to show the others?

The tab of updates says tha there is no updates but if i search individually for an app it says to update!
