Layered Blend Per Bone node doesn't update immediately when adding Branch Filters

When adding Branch Filters to a Layered Blend Per Bone node, the Details panel will not updated immediately. The user will needs to deselect and select the node again to see the added filters.

So far I've only been able to reproduce this issue with this node.

1. Open QAGame in editor.
2. Open any animation blueprint in editor.
3. Add a Layered Blend Per Bone node.
4. In the Details panel, add a Branch Filter.

RESULT:

Details panel does not update.

WORKAROUND:

Deselect the node and select it again. The filters will now be visible.
