Anyone else have shortcut challenges that could never be unlocked?

Ive been playing Hitman since Absolution. I dont know how my saves from H1 and H2 transferred to H3 or whether I even did it.

But my Dartmoor Shortcut Ladder is unlocked and usable, while the Challenge for it stays locked. I searched for people having a similar issue in the forums, reddit etc. but didnt really find anything.
I contacted support and told them I already did the following:

• Started  a new dartmoor mission, interacted with the ladder (went up and down multiple times), finished the mission, no unlock.
• Started a new dartmoor mission in offline mode. The Ladder is locked again, but unlocking the ladder and finishing the mission doesnt unlock the challenge as it is offline mode
• Tried loading the offline save where the ladder is still locked while online, this does not work because the game forces me to play that save in offline mode

They then suggested this:

• Make sure your internet connection is strong enough, and if you have this option, ensure you are using an ethernet connection
• Make sure you have installed the latest updates for the game
• Verify game files
• Back up your save files and perform a full reinstallation of the game
• Run the game as Administrator

Did all that too and the Challenge stays locked.
Support then told me they forwarded it to the Dev team but I honestly doubt much will be happening.

Did anyone else encounter this? Were you able to solve it somehow?

Its not like I need this challenge to 100% the game on steam, it just bugs me.

Thanks for any tips :)
