Doesn’t hide Meta Tag Manager menu item

Activate the debug helper in Adminmize and log in as ‘editor’, open the console F12 in your browser and check the slugs. I think the plugin have an other slug for Editor-Role Login, so that it is not possible for Adminimize to add this to the settings. Adminimize read all menu items with your admin role. If the item slug is different, please add it as custom item and use it to hide, like this how to: https://wordpress.org/support/topic/hide-visual-composer/
