Hi
I would think that if the 2nd policy was only to cover the extra borrowing, which has now been paid off, then there may be no value in continuing the 2nd policy.
However, before you cancel, you should speak to the company concerned, to see if there is any technical issue, that would make it sensible to continue the 2nd policy. If there is no issue, then atleast you would have talked to someone at the company and have some confidence about your decision.
