Discrepancies in Binance Historic data

There appear to be significant discrepancies in historic data for Binance 15m BTCUSDT Kline futures.
Data downloaded from data.binance.vision/?prefix=data/futures/um/monthly/klies/BTCUSDT/15m

  1. March 2 2021 (2021-03-02 01:00:00.000Z) the number of trades and volume differ greatly from the prior kline (ending at 00:45:59.999Z). Then the next 3 klines all have no price changes and zero volume (the final ignored field is not shown here).

    (01:30 and 01:45 are identical to 01:15 kline other than the time stamps)

  2. for 1 January 2021, data from the historic file does not fully match either the kline from
    fapi/v1/klines OR fapi/v2/continuousKlines (PERPETUAL contract type):

Prices from historic file match Prices from fapi/v1/klines but Volume does NOT.

Volume from fapi/v1/klines and fapi/v1/continuousKlines matches but Prices do NOT.
These glaring data discrepancies at the least do not bolster confidence in Binance data integrity, and without data integrity everything else is also suspect.
I do note that there appears to be consistency with current klines (fapi/v1/klines and fapi/v1/continuous klines, retrieved today December 25).
Questions:

  1. Will these issues (e.g., the zero values in March data) be fixed?
  2. Is the URL I used for historic data (manual downloading zip files by month) correct?
  3. What is the difference between Futures klines (fapi/v1/klines) and fapi/v1/continuousKlines with a contract type of PERPETUAL?
    On the face of it, it seems to me they are/should be the same.

Please raise an issue here.
