Big Logos fine, small ones - not so much

So I used the resource archiver to extract the graphics files for FM2020 and have then added some of my own pics and logos in a created a new graphics.fmf.

Everything worked fine with uploading a few player faces and a couple of logos but now that I have added all the logos that I would like, the small ones that show up in the tables dont want to work. The larger ones when you click on each individual team are fine though.

I thought it might be because I had copied and pasted the config file so that I didn't have to type everything out twice but, looking at the FM19 graphics extract, that seems to be the exact same file. So I'm really stumped.

Any help would be appreciated
