Can’t view the column

Good day!

I’m planning to install WC Restore the Purchased items Column in Order Page plug in our production website. But before actively install, I’m testing it on the staging site. I cannot view the Column of Purchased items in Order page. I already deactivate one by one all the plugs but I did not see any plug/s interfering with it. Hope you can help me sort this out. Thanks.

Respectfully,

Billy
