Workflow - recall & Approval

Hello dear all,

i have a strange case with the workflows in a PO:

1º workflow was submit

2º workflow was recall

3º workflow was submit again

But the weird part is that the approval manager reports that he sees in his "work item assigned to me" - 2 approval requests.

(take into consideration that the 1º approval request was recall) , he should only see 1 to approve.

Any ideas why this happen??

thank you
