Why does 2019 TT calculate share of different expenses differently for a vacation rental which has personal use? Shouldn't the share of expenses should be consistent?

Vacation rental expenses are limited by income.  Here is how the IRS puts that-

If you use the dwelling unit for both rental and personal purposes, you generally must divide your total expenses between the rental use and the personal use based on the number of days used for each purpose. You won't be able to deduct your rental expense in excess of the gross rental income limitation (your gross rental income less the rental portion of mortgage interest, real estate taxes, casualty losses, and rental expenses like realtors' fees and advertising costs). However, you may be able to carry forward some of these rental expenses to the next year, subject to the gross rental income limitation for that year. If you itemize your deductions on Schedule A (Form 1040), Itemized Deductions, you may still be able to deduct your personal portion of mortgage interest, property taxes, casualty losses, and rental expenses from federally declared disasters on that schedule.

Here is the original IRS topic.

I knew all that, but as I said, it seems TT is not calculating the share of expenses consistently.  Also, the carryover seems wrong.
