New added link categories are showing up with larger fonts & different bullets below

I added new link categories. The fist one the title category is one size font but all the others are larger.

The bullets on the first link are bar bullets. The other new categories that were added have the larger title font and the bullets are little dots.

Can anyone explain how or why that happened and how I can fix it so that all the fonts and bullets are the same (the bar bullet)

Thanks
