Can't close/cancel contract. Billing event recycled.

Hi helpful people.

(Please see attachment).

We are unable to close contract 0009340 because we must first mark the Bill Plan as complete.  We are unable to change the bill plan status because there is a billing event with a “recycled” status.  How to find out what caused it to go to recycled?

When we try to complete.  We get the message.

"The bill plan has events that have not been Completed or Reversed."

When we try to cancel.  We get the message.

"The Billing Plan cannot be canceled until the Cross-Reference table amounts net out to zero".

What is the workaround to resolve this so the contract can get closed.
