TOPIC: Multiplication of the scheduled actions

Since last three months I have a problem with the uncontrolled multiplication of the scheduled actions in one project.

For example I have an action scheduled once per week without the end date. This action has been running since 2010.
Unexpectedly, I started having new instances of all the actions since 2010 again. If I don't delete them next time I have 2 copies of actions from the 2010.

I've tried changing, deleting recurrency, in vain, after the next start of the TR these actions are scheduled again.
Only deleting the project helps.

However, after deleting the project with the scheduled actions, the problem repeats itself in the other project with the other scheduled actions.

It's really annoying to combat against this uncontrolled multiplication.

What can you advice?

I have Windows 7, since last week I am using the latest version of the TR, previously it was as well TR 3. something.

I had the problem once when I changed time zone. The only way I solved it was my deleting the recurrence, action and re-create it. But there might 2 recurrence definitions and by only deleting the project, you are sure to have deleted both.

If you send us your data file, I can ask the developer to look at it.

By the way, I agree it is very annoying.
