Updateing the collection worked fine for me in the Beta. But since a few days i can't update it anymore in the Final-Version.

I'm using a Samsung Galaxy S2 with Android 4.1.2

Here's a video where you cann see the bug :

Since you are syncing via the online collection your Online Collection settings would be more important. Please check if all visibility options are flagged (Adult must be flagged for Public and Private).

On a side-note:
What I found strange about your video is that your progress-bar is yellow, isn't it supposed to be green?

Nope, my progress bar is yellow.  It might be dependent on the Android OS.  i'm using 4.2.1 on an Asus Transformer Infinity.

But back on topic, my collection downloads correctly.  F1Database, have you identified the two affected profiles?

How to check that?
Please check if all visibility options are flagged (Adult must be flagged for Public and Private).

I changed nothing in the databse in the last days, just uploaded some new version of profiles via pc.

In the app make sure the user settings are set to include all profiles.

Settings -> Users -> (select user)

Turn Principal User -> On; Allow Adult -> On; change Rating Age -> 21+

However, if you haven't added any new profiles, only updated existing ones, then the count discrepancy doesn't make sense.  Have you tried a database repair and then reupload to the online collection?

What does principal user means?
It is on "off", and "Allow Adult is "off" and Rating Age is at "18+". I didnt change here anything.
But how do i store here changes?
If i change something and leave this page and go back, its all set back to those options.

Principal user means the main or chief user of the database.  If you're the only user then you're the principal user.

To save changes you need to select the blue checkmark icon that says Done next to it.  You should be able to find it in the upper right corner of the app.  If it's not there try the menu button to see if your device moved it there.

EDIT: An example screenshot with the Done option can be seen in this post.

Example

i uninstalled the application and deleted all the files.
Then i did a new install and downloaded the the collection over night and now everything is fine.
I hope it stays this.
