Okay, I tell you what I found about enum flag step by step.
1. Create FSM with GraphOwner
2. Create TestAction in FSM what we created.
3. Change value as Hello of enum value in TestAction
4. and save it as asset named “sampleFSM.asset” in project folder
5. open the “sampleFSM.asset” in text editor.
5. you will find the weird behaviour of serialization.
