by the month, so when a girl leaves and another one replaces her,  but there is still time left on the ad that has already been paid for, they just insert the information for the new girl in the existing ad.  That's why the "Llikes" don't start over when they put a new girl into an existing ad.  In this case, it looks like the booker is asleep at the switch or else hasn't finished switching out the ad yet.  Should be fixed soon.  Booker may not have realized it.  If you text the booker and tell them the ad isn't showing the stats, they will probably fix it sooner rather than later.
