My bush trip's progression is gone after Sim Update 5!

For those that lost the landing challenge progress, please also see:

All Landing Challenges gone?

I did all Landing Challenges some time ago. Now in new Challenges Menu I see Landing Challenges: 0%. And each one is marked as not done. Is there something I can do to restore them? Bush Trips works fine - I see my progress there.
