Delete Wrike Tasks instead of just Recurrence

We are using recurring tasks quite a lot and are finding them confusing. If we delete a recurrence, it often times deletes the original task as well. How can we prevent that from happening so that we still have the original task and are ONLY deleting the recurrence? 

Additionally, the options to start, end and 'limit to' are confusing. The functionality seems inconsistent and we are not completely confident in recurring tasks, but we need to utilize them. 

Lastly, we would love to have a project with recurring tasks as a template; but when we kick off a templated project from a request form, the recurrence does not remain and we have to re-build each time for hundreds of tasks.
