DataLayerValue pagePostType

Hi, I’ve successfully applied the GA4 / EEC Tracking on a site, like I did with a lot of other sites. Unfortunately I have trouble with one dataLayer value, the “pagePostType” shows “product”, even if it’s a product-archive / product-category page.

What can cause this or ist this new and correct behaviour?
