Help updating to Payplans 3.7.1

Hi SI Team

I feel really stupid but I do not know how to update Payplans.

I do not see an update button similar to Easy Social or Easy Blog in the Component section.
And I do not see the option to update PayPlans with the standard Joomla extensions manager.

I also have a message “Either no data available or do rebuild stats if not done once.”

So I clicked the “Rebuild Stats” button but still nothing happened.

What am I missing

thanks

Paul
