BuddyPress / BuddyPress Sliding Login Panel Issue

I am currently using the “buddypress sliding login panel” plugin and am having some issues. The panel opens fine but does not close. I can’t tell if there is a conflict with BuddyPress, the studio theme or simply a plugin issue. This plugin wasn’t made by WPMUDEV but it was made by your excellent blog writer Sarah Gooding. Does anyone know what could be wrong?

Thank you.
