Some of K2 items I create can't save the Metadescription I use. I change it in database, also in the editor but the item is taking the category metadesc.

Please can someone help me?

There is an Example: Destinos Baratos de Europa: Rumania

I found the cause of this issue:

If you got a menu link to the category and you are using meta-descriptipn field of the menu, all the items in this category will use this meta-description. I don't know why but in my site is what happens.

Using K2 meta-description field works pretty good.

Regards.
