GCalendar and Library installed but still getting error

I have the Google library installed and used the one that came packaged with OS Services Booking.
If I go to cancel and order or delete a canceled order I get the following error message.

"OSB set to use Google Calendar but the Google Library is not installed." 

I have filled out all the info that it asks for when turned on. I also has created an App in Google and all the required accounts data requested.

Hi Jeff,
Please submit ticket on category: OS Services Booking and provide your site url with super admin account. I'll check the issue for you
Thanks

Thank you for responding Dam. The issues resolved itself due to a caching issue. I couldn't find where to delete or remove this subject so that you wouldn't have to be bothered.
Thank you for your time.

Ok Jeff
