Incorrect disabled veteran exemption values in database

[AleaWM]

the pin table in the database appears to be missing values for some PINs that received disabled veteran exemptions. These values appear to be missing in multiple years. Values are recorded as 0 instead of the amount of EAV exempt.

tax_bill_total in pin table of database is correctly recorded as $0, homeowner exemptions, senior, exemptions, freeze exemptions, etc, appear to be correct.

tax_amt_post_exe, final_tax_to_dist, & final_tax_to_tif created with tax_bill() is also incorrect for some of these PINs.

PIN examples:

• 31274090020000 (missing 2016-2023, tax_bill() has total_billed value of $4,554, includes correct exe_homeowner amount but missing disabled veterans exemption amount in pin table)
• 06134050330000 (missing 2020, 2021, 2023 in pin table. creates incorrect final_tax_to_dist, total_billed, tax_amt_post_exe from tax_bill() for 2023, has correct exe_homeowner amount. COE in 2022 not reflected)
• 17344230080000 (missing 2018-2023)
• 02214040310000 (missing 2018-2023 and tax_bill() shows a tax bill of $24,478 for 2023 instead of $0.)
• 05204080120000 (missing 2019-2022, COE in 2023 not reflected)

1. A follow up comment explaining how this was identified:

Subtracting the exemptions from the eav in the pin table results in post-exemption EAV values that would not result in a tax bill of $0. Around 7,000 observations were identified with large amounts of "remaining" taxable EAV after exemptions that still had a $0 tax bill. Exemption values and taxbills were checked online to see if there was some nuance with the tax bills that was not included in the PTAXSIM database. While doing this, the only reoccurring pattern identified were PINs that appeared to be missing the amount of exempt EAV for exe_vet_dis_ge70 that would wipe the remaining taxable EAV to 0 and result in a $0 tax bill.

2. A list of example PINs that are slightly more thoroughly recorded and maybe easier to read:
