How to delete Reserved by Gcal entries

I am very happy with the Gcal integration option however… I integrated gCal today with Appts+ and it only took one item from the calendar and created it 100 times (every month for the next many years) and inserted those into Appts+. Not sure why it did this but it skipped over the bunch of appointments in my gCal and picked this one that is one month in the future and recurring.

I want to delete all those recurring Appts+ entries as they are kind of bogus and did not see anywhere to delete them in bulk from the list – only to remove them individually.

Also, need to find out why it only selected one item as opposed to all my calendar entries.
