Returns - check out products

[LCortes]

Dear all

I'm trying to configure returns. I activated it in back office and the option is only visible to costumers and delivered items. All ok!

I'm sending attached photo to show the list to choose desired items to return.

I think that would be nice and easier if that board has one check box to choose items to return. Is my Niara theme that is hiding it (like it did in "accept terms" in checkout) or simple isn't there?
If Niara is hiding my check box, how can I unhide it?

Many thanks
