Unable to Edit Menus

Hi there,

I just upgraded to the latest version of WP (was having this issue in the previous version, as well), and I am unable to edit my menus. I am able to move the pages on the menu around, but there is no arrow to click to reveal more options so that I can delete pages/edit their titles. I would appreciate any help I can get in addressing this issue.

Thank you!
