work confirmation duplicated

Summary:

I have two issues related to work confirmation

1.

I have created a work confirmation in which the work confirmation appears Approved and Pending Approval

as appears in the first section in the image

2

another case in which the work confirmation is withdrawn then canceled but it appears as two documents one canceled and the other pending approval, and when I login the Pending approval it appears cancelled

appears in the lowest section in the image

How to resolve this issue ?
