STEPS
-----------------------
The issue can be reproduced at will with the following steps:

1. Create a tracking event agent.
Agent Type = Tracking Event
Agent Events = TRACKING EVENT – CREATED (Restrictions – User, Before Persist - true)
Actions – PERSIST
Save

2. Create a Tracking event.
Fleet Management – Visibility – Tracking Event – New
Insert any data, press "Finish".
