MAJOR BUG - Campaign Potentials are not fully deletable!!!

I am busy working with the campaign module and have found a bug regarding all potentials that are attached to a specific campaign. Zoho does not allow these potentials to be fully deleted. After deletion the potential can still be found by running a report on existing potentials. It seems that zoho only partially deletes the potential but does not delete the Amount. Now I have potentials floating around in the system that have an amount but no contact/account or name. This effects all potential reporting within the system

I created a potential within my marketing campaign module called "test" which is assigned to a contact in zoho with a value on 1000,- EUR. Afterwards I deleted the potential, all seemed to work corrrectly!!! HOWEVER when I run a report on open potentials I find a blank potential (without a contact or name) with a value of 1000,-EUR. This completely screws up all potential reporting etc!!!
