Collection dropping from COLLECTION TYPES and api routes becoming authenticated on its own

Lets say I logged in on strapi admin using super admin role and created a collection Type REVIEWS. I added some data to collection REVIEWS and made its find and findOne route public from settings > USERS & PERMISSIONS PLUGIN > ROLES > APPLICATIONS.

Sometime this collection REVIEWS does not appear on strapi admin dashboard. If It is appearing on dashboard, its related api routes find and findOne becomes authenticated on its own.

If anyone has faced the similar issue please share the wisdom.
