Ads not showing when selected Before Comments

Hi,
Hope you all are doing well.

The plugin is working perfectly and it is awesome. I am facing issue when I am trying to place a banner ad just before my posts comment.

If I place it after comment, it is working fine. I don’t want my ads to go below comments as visitors will never go down the comments to see ads.

Kindly help.
