Discrepancy in subscriber limits

Discrepancy in subscriber limits

Hello,
My Zoho campaigns dashboard shows that I have 8863 contacts subscribed.

I want to add a list of 993 subscribers and I get a warning saying that I have 9602 subscribers.

My subscriber limit is 10000.

Could you please tell me what is going on? I need to act quickly and do not understand why there is a difference between the warning and the number of subscribers on the dashboard.
