Description

Migrating from 1.15.x to 1.16.2, losing the inherited relationships between Parameter Contexts in the following scenario:

From what it looks like, any Parameter Context that was inherited multiple times did not stay inherited.

Ex.
Parameter Contexts A,B,C,D

Before Upgrade:
A inherits B and C
B inherits none

C inherits none
D inherits C

After Upgrade:

A inherits B

B inherits none

C inherits none
D inherits none
