Ticker information incorrect for some symbols

Result

vestedus.polygon> (ticker-details "ULTR")
{:cik "0001415995",
 :locale "us",
 :composite_figi "BBG00PPRNFN3",
 :name "IQ Ultra Short Duration ETF",
 :ticker "ULTR",
 :primary_exchange "ARCX",
 :type "ETF",
 :share_class_shares_outstanding 2049999,
 :list_date "2006-10-13",
 :active true,
 :currency_name "usd",
 :share_class_figi "BBG00PPRNGD2",
 :market "stocks",
 :ticker_root "ULTR"}

Expected Result The ETF ULTR's list_date is 2019. In this case it is picking the list_date for a ticker listed on a different exchange. This breaks being able to get the history of a ticker using the agg API due to a similar issue.

Thanks for raising this issue, we're investigating the problem now.

Unfortunately, there is no update at the moment. This is something that is surfaced relatively frequently, so I can assure you its on our radar.

You may be able to use our Ticker Events endpoint for the list date instead of ticker details:
