some Logos aren't showing. Help!

Hello.

I downloaded a logo pack for my Fm 17 and I noticed some logos aren't showing. The logos include Swansea, Leicester, along with all the country logos. None are showing while some of the logos only show when I'm playing a match e.g the logos from la Liga and seria a. I've tried everything but still nothing seems to work. I know there's a problem somewhere but I cannot seem to find it. Help!
