It appears the other ad code was removed since earlier today. Did you remove it? There were definitely two different IDs on the post pages I looked at earlier & the 1st ID in the source didn’t match the ones below or the top one in your ads.txt file.
Cached page that has the other ID but that one is no longer on the live page.
Your posts pages have more than one publisher ID on them & Adsense will count page views in only one account. Thus one account will show page views while the other(s) won’t. However they will count impressions & ad clicks for each account that they happen in so your page CTR gets distorted.
