It looks like the Austro-Hungarians liked the Knoller-Jaray prop ..

Much obliged my friend! 🤜🏻🤛🏻🍻
That's some weird props, made me think of contra rotating propellers first, but it's too early for that, isn't it? 🤨🤔

Why this way?

A couple of sources says that the propeller was the contra-rotaing prop. But in fact , it wasn't. The images with the W.K.F. Dr.I in, clearly shows the spinner doesn't allow to move the two props separately. IMHO the prop was used because of the power plant to limit the head drag and keep the correct trust to the engine maximal power.

And more info ...

The special four-bladed propeller actually consisted of two two-bladed propellers intentionally not mounted together at 90°, as clearly visible. An Austro-Hungarian patent covered these propellers, which were produced by the Jaray propeller factory in Vienna. This type of propeller was only used by the Austro-Hungarian forces.
