I just did some testing, but I’m not sure if I can reproduce the issue. I’ve enabled “Per product” settings and added a quantity discount for product A and no discount for product B. Then, in the “Info” section, I’ve enabled the “Single product page” option and set the template there to
[alg_wc_product_ppq_table]. Now product A does have a pricing discount table displayed on its product page, and product B doesn’t have it. So it looks ok here? Or did I misunderstand the question?
P.S. If possible, please share access to your site, so I could log in and check what’s going on (my email is [email protected])?
