plugin breaks menu title attributes

I’m using WP 3.6 in a multisite arrangement with wp e-commerce 3.8.12 only enabled at the site level (not through network dashboard), and when this plugin is enabled, it adds additional <p> tags to the Appearance > Menus > Title attributes and breaks some custom dropdowns I have written with javascript that calls the menu title.

If disabled, saving the menus, and then re-enabling the plugin, situation is corrected
