For some reason, from my content module, items located in one of the categories is linking to:

component/k2/item/

It loads the article fine but without all the other modules it should have around it.

This is strange because all the other items which are located in other categories are being linked to fine from the content module.

articles/item/

I have checked and doubled checked all the settings for this category and they all appear the same as the others, but there is this SEF issue from the content module.

Any ideas???
