Tesla stock price history is incorrect

Question

When I update security quotes, the Tesla price history contains spurious values. Rebuilding the price history does not work either. This just started with the stock split.

See "Hierarchy for prices entered" here:https://www.quicken.com/support/how-update-security-pricesI'm assuming this hierarchy is the same for Mac.I guess that the periodic "spikes" before January are the erroneous Friday quotes?  Try entering a few of those quotes manually to see it they come back with the next update.

I removed the erroneous TSLA quotes from price history, and everything looked OK until I did an update today, see attached. And also seeing AAPL quote errors.
 Several questions;
 - who is the Quicken stock quote provider?
 - during an update, how is the price data from the FI (Fidelity, Schwab, etc.) used? What takes preference?

TSLA stock price for most every Friday in 2019/20 is off by almost a 5X factor. Looking at Q price history prior to 2019, the pattern is much more erratic.I would have thought that Q, or Q data provider would have caught that and made a fix by now.

I just rebuilt TSLA price history and it is way out of whack!!
