@Angela104 As others have said, your weekly/monthly discounts are much too high! 43% off for a week and 61% for a month? Of course smart guests are going to do a little math and figure out, for example, that if they want to stay 4 or more nights, it's cheaper to book the week. Or if they want to stay even just two weeks, book the month. I don't mean to be harsh, but you have no one but yourself to blame for not thinking your discounts through.
A little math:
1 day is 14.3% of a week. So set a weekly discount to something 13% or less to avoid clever guests booking a full week when they only want 5 or 6 days. Likewise, make sure that your monthly discount doesn't give guests a better price than a 3-week booking at the weekly rate. So, don't set a monthly discount of 30% or higher. (I'm simplistically pretending that a month has exactly 4 weeks, but you get the idea.) Personally, if I limited my weekly discount to 12-13%, I wouldn't set my monthly discount any higher than 20% even I wanted a monthly discount. I don't actually allow guests to book for a full month, so I don't have a monthly discount.
