Minimum post settings keep disappearing(SELFSOLVED)

In the admin panel, my settings for each rank for minimum posts, keeps disappearing. I type them all in, save them all, and then when none of the ranks were increasing according to the parameters of minimum posts, i looked pack at the minimum numbers and they were gone (in admin ranks config). On the list there of ranks, the column under minimum posts has a dash/blank spot because the minimum numbers simply aren't saving. What could the problem be?

Okay i figured it out myself...i had the ranks all set to "special ranks" and this precludes setting a minimum number of posts. I unchecked the special rank/making it NO, and then entered the minimum number of posts for each rank again, saved, and viola!---it's now working.

thought this might help someone else.

"Special Ranks" is for special titles that can only be applied by an admin. :-))
