This is the standard behavior.

1. Ordinary depreciation amount in tax area 15 is calculated as -83 JPY and in book area 32 is calculated as -70 JPY, then NBV of derived depreciation area 92 (tax area 15 - book area 32) becomes negative (-13 JPY), this means depreciation shortage occurs (Q5 in FAQ Note 1736835 explained depreciation shortage)
2. To resolve depreciation shortage, ordinary depreciation amount 13 JPY is automatically set in tax area, then NBV of derived depreciation area 92 becomes zero (not negative) and there is no depreciation shortage. So ordinary depreciation amount (-83+ 13 = 70 JPY) is displayed in tax area 15.
