Schedule E error - days personal use cannot be more than zero

I rent out part of my house (30%) as a AirBNB - last year, it was rented for 44 days.  The remainder of the time I use that portion of the house (and I DO use it, it is not sitting vacant) for personal reasons.  I put in this split in order to appropriately prorate my taxes/interest, etc and those numbers all looked correct to me.  However, when going to submit I get the following error: "Days personal use cannot be more than zero.  You indicated that this is an owner-occupied rental property."  If I change the days personal use to zero, than it attempts to deduct a full 30% of my mortgage interest and property taxes as rental expenses, even though the rental portion of the house was not rented out the entire year.
