invoice approval notification shows previous invoice detail

Hello Experts,

My user is facing the issue while approving Invoice, like whenever he is clicking on Invoice X Approval notification first time he is able to see correct invoice detail and approve it. But when returning to home page and clicking on next invoice approval notification then he only see the invoice detail of invoice X not Y.

In simple, first whatever invoice approved the same invoice detail appear on consecutive invoice approval details.

Kindly help me if anybody faced the same issue.

Thanks,..
