[Plugin: Events Manager] Event Manager

I am having a problem with Event Manager and the Wp-Full Calendar plugin as well.

All the cells on my full calendar are like they have a large padding or margin and are only filling out a small amount of the cell. See https://nativitycatholicschool.org/build/campus-life/school-calendar/ I am having the problem with Events Manager without the plugin, and had to mess a bunch with it and negative margins, but when I added the plugin it came back- Im not sure where it is coming from?

Anyone else had this issue?

Thanks!
