Google calendar entries on Android phone

[AC Question]

When I enter and event on my android phone it disappears immediately. It does not appear on my laptop gmail calendar either.
I have tried deleting the app and re-installing with no luck
I have checked when entering and it shows event and my email (gmail) address. There are no other options showing.
My phone runs 5.1

But if I enter a reminder it stays and also shows in my gmail calendar on my laptop.

Help please
