Two event graphs with similar names will populate events to only one graph in My Blueprint pane

Two event graphs with similar names will populate events to only one graph in the My Blueprint pane. This specifically occurs when the event graphs are named with and without spaces in the name, such as:

Eventgraph Test1

Eventgraph Test 1

Both can be created and compiled with no warnings or errors, however adding events to both will only add events to one of the two event graphs.

1. Open Editor (any project)
2. Create new blueprint
3. Create two new event graphs, one named "TestSpaces" and the other "Test Spaces"
4. Create a custom event named "Test1" in "TestSpaces"
5. Create a custom event named "Test2" in "Test Spaces"

Results:

Both events appear under the event graph "TestSpaces" in the My Blueprint panel

Expected:

Event "Test1" appears under "TestSpaces" and event "Test2" appears under "Test Spaces".
