Allocation of Property Tax Between rental expense and personal expense

I rent my primary residence as a part-time vacation rental during the summer. When entering my property taxes, the allocation to rental expense is correct but the allocation to my personal deduction is listed as a vacation property, not taxes on my primary residence. If I override the allocation and delete the taxes for a vacation property and allocate it to my primary residence, I get an error message on my Federal review. How do I fix this?
