How to delete unapplied cash receipt with future year GL date ?

Hi - Please see the issue we are facing :

1. The user created A/R receipts entry for an existing invoice using GL date and receipt date of September 2019.

2. The A/R receipt was posted to GL.

3. The A/R receipt was voided , which in turn created a new batch.

4. This batch was posted to GL.

5. Now the system shows unapplied cash receipts in the system.

We would like the unapplied cash to removed from the system. It will be great if  you can please provide the steps to perform this.

Thanks.
