Approve Purchase Order shows request zero

Hello,

I am implementing Approve Purchase Orders

its an embedded landscape EHP7.

I have installed all the add-ons and activated services.

i got data created for PO which I am able to view on sbwp for release.

But I am not able to see request on Fiori Application .

I check the iwfnd logs but it shows no error also st22 shows no dumps.

I tried to check inspect element in chrome. Below are the details
