Pretty Plugin not forcing upgrades

I seem to be running into an issue with Pretty Plugins. We have 5 tiers of supporter levels (5 being the most features). When we assign someone to the middle 3rd level and have pretty plugins activated that 3rd level user can activate plugins that should only be available to higher plan members. The plugin does display the Red text that says “Level 4 Only” and that links to the upgrade page, but if you click directly on the image assigned to the plugin, the plugin is activated and running with no restrictions.

I’ve double checked and every single plugin and core are up to date btw.

Any thoughts as to why it might be performing this way?

Thanks so much
