Why I cant see my registered users in members page?


I just installed bbpress/buddypress on my site and everything seems to be working fine but when I click the members tab I am the only member, even though I have 87 registered users on my site.
Just in case, I turned off my wishlist member plugin but the results were the same.
Shouldn't all my wp users be displayed as members?
Do I have to activate them somehow?
What am I doing wrong?
By the way, "Enable BuddyPress to WordPress profile syncing" is checked in buddypress settings.

Thank you for your help,
