No ILS Bugs visible in the PFD

[350Pilot]

Hi, suddenly there ar no ILS Bugs visible in the PFD. I switched CPT and FO ILS Switches to on and tune in the appropriate Frequency.
But it seems, the ILS would not be received in the A306 PW.
Normally i fly Approaches by Hand. Thats no Problem with nice Weather. But in heavy Weather it is extremely difficult to land without the ILS.
This occurs on every Airport.

 
Are there any Suggestions, how to solve the Problem please?

Greets,

Here is a Pictures. They are from the Final Approach to 08L at EDDP.
But as written before, this occurs on every Airport.

Hi there!

Have you noted this behaviour in any other aircraft? Did this start recently? Those questions aside, please make sure you have updated to at least REV 2 cycle (I believe Rev3 is the latest) in the Navigraph hub, if you have that. 

Thank you
