add to db not works first time

[z85510]

When the app starts and I am clicking on the float action button, nothing happens on the list for the first time.

When I tapped the button again then I can see the first item but if I close the application and run it again then I can see two items, the first tap has worked but the list hadn't been could refresh.

The list needs to refresh but I don't know why and can I fix it?

in this gif, I'm showing the process if I update one of an item which means I refreshing the list so then it will appear.
