Tab header for only one screen in screen set

Hi, all,

I am working with SAP Work Manager 6.0, WPF Client.

Sometimes, upon a new client installation, or a client reset, the layout is somewhat screwed up.

If a screen set has only one screen to display in a tile, there should not be a tab header for this screen. Normally, this is ok, but sometimes my screen looks like this:

Two tiles on the botom right have only one screen in the screen set, yet the tab header is shown.

Has anyone else experienced this also? What can be done about it?

Thanks in advance

Kind regards,

Judith
