Grey Line at bottom of Div Block

[hg_1437 (Hannah)]

Hey guys does anyone know why there is a grey line at the bottom of this Div Block. It seemed to have been added automatically when I added Link Text inside the Div block, so they are probably connected in some way. Can anyone let me know how to resolve this? There is no bottom border set.

I see it on the collection item element. Not sure how it got there automatically but that’s where it is if you need to remove it.
