Welcome, @Laya_Liebeseller,
The limit applies to all people in your org/workspace, not in any one project, so I think that may explain it. If not, please try these troubleshooting steps, then please 1) report your problem by going to Report a Bug, clicking the New Topic button at the right, and following the instructions, or 2) contact support directly with these steps.
