Mass Planner Follows

Hey guys,
I've been using Mass Planner for quite a while and this problem has never happened to me before, but all of a sudden a few days ago I noticed that some of my accounts face a error on Tools->Follow saying "Sorry. You're following the maximum limit of accounts. You'll need to unfollow some accounts in order to follow more". So I went to check how many accounts they were following and I saw that none of them even go near 7500, I got no clue for the reason of that happening...
Does any of you know why?

How close to 7500 are they? Do you follow private users? Those still count towards the number even if they havent accepted the request yet I believe...

They are around 3-4k, Can't believe they are awaiting 3k personal followers.
Anyways I just blocked following private profiles from now on.
