When you set up a calendar rule to copy events from one Google calendar to another, the rule will only copy the events that where you are busy in the previous and next 6 months.
Check that it should be copied.
Ditto Call will NOT copy the event if any of the following are true:
If you have checked this and there is still a problem copying the event then please get in contact and I will see how I can help.
If you make a change to one of your Google calendars which is a source for copying from, then Ditto Cal will copy these changes to the destination calendar within a minute or two.
If you check the "Merge copied events where possible" option for your calendar rule then it will merge copies that overlap or are less than 10 minutes apart. This enables you to share only your availability with the destination calendar.
When you delete a rule for copying availability between two of your calendars Ditto Cal will delete all the copied events that it created in your destination calendar.
