I honestly don't monitor the humidity inside my curing jars except to actually FEEL the buds when I open the jar to burp them... It sounds to me like your buds are not as dry as they should be leading to the increased humidity. Take the buds out in the morning and lay them on a plate or screen in a single layer and leave them for the day... check how they feel as the day goes on and then put them back into the jar with the Boveda pack.. Check them again the next day when you burp the jar... if necessary, give them another day outside the jar... and keep doing this until their moisture content stays the same...
As a side note here, you might want to investigate Grove bags... I haven't used them myself but others who have swear by them... apparently they're kind of a "put the bud in the bag and forget them" kind of thing ... I just find them a little pricey and don't mind a little bit of extra work 'cause I have more time than money! :-D
Good luck!
