We are not sure what you are referring to, but it seems like you mean ATTRIBUTES.

These can only be applied by a PERSON... the software does not suddenly, of its own accord, decide... "Hey... I think I'm going to give every product some attributes... !"

a PERSON has done this... so only a PERSON can un-do it.

If you do not want to show ATTRIBUTES for a given product, then (via the attributes controller) manually delete them.
