Custom Events create in Blueprint in 4.6

In 4.5.1, when I defined a event dispatcher which has two parameters in a blueprint class, if I want to bind event handler to a class instance, I can just drag the red node at the left down corner and select “delegate sth. sth”, And the engine will generate a event node with parameter list which is corresponding to the parameters I have defined in the event dispatcher. But in 4.6, whenever I drag from the bind event node, only appears a custom event node without any parameters.

In 4.5, the custom event was able to be selected from a function list in a blueprint, but now I cannot create the node. But the old event nodes still works and can be copied.

May be I cannot find the node or it’s removed in 4.6?
