Why are the areas for modules not displayed in the opencart product card?

Question

opencart

Hello! I'm making a store on OC. For the test, I loaded a product on it. The product gets to the site in 2 ways: directly from 1C and one category from csv via CSV Price Pro import / export 4. Those products that are loaded from csv are displayed incorrectly ... on the page of these products, no areas for modules are displayed at all .. neither right nor left column, neither top nor bottom. Regardless of what modules are inserted there, at least a banner, at least a category.
Switched to the default theme - still the same.

I don’t know how it is connected, but after I finally set up seo-pro, the problem was solved (before that it was installed, but it didn’t work and there were some errors).
