CSS Issues X 2 - Menu Display / Clear Fload

Good afternoon --
I have two CSS issues and I feel silly for asking, but I've looked at the computer screen long enough.

https://cityofhanahan.com/government/police-department/divisions/k9/

On the above referenced page you will notice that the "Retired K9's" is picking up on the float:left from the "K9" section which is dynamically generated by a staff directory plugin. I need the "Retired K9's" to drop to another line.

Secondly, I added a border to "sub-menu" for appearence, but now I need to remove the border from the sub menu with children as in https://cityofhanahan.com/government/police-department/divisions/k9/ where you will see the menu on the left also has a black box surrounding it for the child menu.

Any help would be greatly appreciated!
