In Animgraph, Custom Blend Logic set to "Delayed Freeze" causes duplicate "Frames to Cache" field

In the Animgraph of an AnimBlueprint, Using Custom Blend Logic results in the "Frames to Cache Pose" field being duplicated if "Delayed Freeze" is selected.

However, if "Standard" or "Freeze" is selected, the "Frames to Cache Pose" field appears only once.

1. in Animation BP, animation graph, state machine, custom blend logic, edit blend graph, select:
"Get Source State Pose" and/or "Get Destination State Pose"
2. Navigate to Evaluator Mode
3. change it to "Delayed Freeze"

this will result in appearance of the 2nd and same property "Frames to Cache Pose"
