Smush Pro conflict with the Store Locator Plus

We have a strange issue with WP Smush. In our WP Admin, we have another plugin called Store Locator Plus in which we're unable to click on anything within WP Admin to change that plugin's content or settings. When we disabled WP Smush, Store Locator Plus started working as expected. So there's some issue with WP Smush that's creating problems within the wp-admin.
