Hi there, @Christopher_Medina 
In the screenshot above, you can see the Event type filters for the manually added events. The Event Type field in Google Calendar looks a bit different from the Event Type in our widget. That’s why the Event Type field and filter are not supported via the Google Calendar integration and there is no way to add it manually, unfortunately.
You can read Helga’s message in this thread to find more details 
Please let me know if this explains things or if you have any further questions.
