After Upgrading to 1.5 can not select item (1 Viewer)

[xadox]

After I have upgraded to v1.5 I am not able to select any button in media portal. I am in Titan Extended. While pressing left or right it is not changing on different buttons but hangs on the current one.

Selecting Titan Basic view I can switch buttons.

Recreating a Titan Extend config with the editor also did not solve the problem.
