Resolution Note (fix version 2021.1):
Fixed in 2021.1.0a3
The observed issue is caused by a misconfiguration of the NavMeshLinks. The NavMeshLink cost modifier should either be:
(a) -1, which instead uses the area type cost, or
(b) Non-negative, which computes the cost as (cost modifier * distance).
