Navmesh Links - Walking

I’m working on a randomly generated city map, each tile is made up of a prefab that has its own pre-calculated navmesh, and uses Nav Mesh Prefab Instance. To connect these tiles, I am using Navmesh Links, which are set to:
walkable,
cost -1,
Autoupdate Position= true,
bidirectional = true.

All generates correctly, the navmeshes are all connected - apart from when a navmesh agent travels across a Navmesh Link he jumps, even though it is set to walkable.

Am I doing something wrong here? I want this to be all seamless to the player, I just want to walk normally across the link?

I have this too, links seem to only be jumps, even on flat ground. Watching this

Unity replied in another thread to say they were going to fix this in an update, I haven’t checked to see if its arrived yet though…
