When swapping Layer settings between various Animation Layers on a Linked Anim Layer node, the node can become stuck in one state. The node will become stuck in the Linked Anim Layer state and cannot be reverted back into a Linked Layer node via the dropdown.
This is not a consistent repro and took multiple attempts at compiling and swapping out various layer entries.
Repro Rate: 3/6
Result: Linked Anim Layer node remains as a Linked Anim Layer node and cannot be changed into a Linked Layer node.
Expected: Linked Anim Layer nodes can be changed into a LinkedLayer node via the Layer dropdown.
