For Rental Expenses: On which Expenses I can claim the Building Permit expense?

I entered in Other but the percentage portion for rental is more than 20% but in calculation it shows only 20%.

In Section" If less than 100% of an expense above applies to the business, enter the applicable percentage." there is no selection of Other so I cannot select the different %.

Please guide.
