Okay, but why are both these templates matching the same elements with the
same priority, in no mode? They are in conflict and your processor will
only use one of them (or throw an error).

I'm not familiar with the mods tagset, but if mods:mods is not a descendant
of mods:modsCollection, this template will never get matched.

Could you show us a small, relevant fragment of your input please?

Unless something I've said prompts you to discover the problem for
yourself, this is one of those problems where we have to see input and
desired output samples as well -- no way to debug the stylesheet on its
own, I'm afraid.
