What:

Start MITK, select two different 4D images (I tested only those with similar 3D dimensions) with a different number of timesteps. Select one of the pictures.
Move the time slider to the very right.

Expected behaviour:
The rightmost position is the highest time step of that picture, which is shown.

Actual behaviour:
The rightmost position is the highest time step of any picture in the datamanager. An output window appears showing warnings.
