Timer does not work in Object Class Blueprint

After creating a timer in an Object Blueprint, timer is not called as intended.
"InitObject" Event fires but "Call Function" function does not

Reproduced in:
4.17.2 CL 3658906, 4.18 P3 3676890

Unable to Reproduce in 4.16.3 CL 3561208.
This is a regression.

1. Create new First Person project
2. Create new Object class Blueprint
3. Create Custom Event called "InitObject"
4. Recreate Blueprint found in attached TestObjectBP image
5. Create Function called "Call Function"
6. Recreate function found in attached CallFunctionBP image
7. Open the level Blueprint
8. Recreate the Blueprint found in attached TestLevelBlueprint image
9. Compile and Save all Blueprints and Level
10. Run project in editor

Expected:
"InitObject" event fires and Object Init printed, Call Function fires and Function Called printed

Result: "InitObject" event fires and Object Init printed, Call Function does not fire
