I was using the Entreprise Free Trial Plan a few days ago, and it expired. After it ended i decided to delete all workflow rules, task and field updates that i created in these past couple weeks during the trial plan. But now i see that i cannot delete them, mainly because Zoho keeps poping-up this message: 'As this task is already associated to the workflow rules, please disassociate it and try deleting.' 

There are no workflows rules left for me to delete, at least visible, and the pop-up keeps showing. I guess that some workflow rules got hidden, and i cannot delete them manualy, and the workflow task and fields update are still bound to them. I was tinkering with the Workflow Rules based on Dates before the trial ended, and maybe these are the workflow that are still there but hidden from me, perhaps because the professional plan doesnt allow their use. 

Can someone inside Zoho delete them for me? I would like to keep things proper before moving-on developing new stuff.

Thank you
