Logged In Users Caching Problem

My users can log in to my website with a widget placed in the sidebar, but when they log in, they see themselves as logged in (what I mean is that they should be able to see the sidebar updating and showing their profile name and picture) only on the page where they logged in and not on the other pages while in reality the login was successful. The only thing that seems to fix the problem is deleting the cache of WP-Fastest Cache. I guess the “Don’t show the cached version for logged-in users” is not working with the plugin I use for registrations which is called “Profile Builder”. I think the issue could be fixed entirely by excluding the user role of my subscribers from the caching plugin. Is it possible?
