Custom Events set to Replicate do not show the replication information on the node until the Editor is restarted

Custom Events set to Replicate do not show the replication information on the node until the Editor is restarted. For example, after setting a Custom Event to Multicast, the "Replicated From Server - Executes On All" information does not appear on the node until the project is reopened. Reliable also does not appear until a restart.

Reproduced in 4.7.1 binary and Main (//depot/UE4/Promotable-CL-2455917)

1. Open any project
2. Open any Blueprint
3. Create a new Custom Event
4. Set Replicates to Multicast
5. Compile/Save
6. Close/Reopen project

Results:
The Custom Event node is not updated until after the project is reopened.

Expected:
The Custom Event node is updated after compiling the Blueprint.
