Historical quotes from Yahoo with spikes

They all have values <1, except for my transactions.

All other trackers from Yahoo return the right numbers, what could be causing this?

Looks like there is a data issue at Yahoo finance: Vanguard Total Stock Market ETF (VTI) Stock Historical Prices & Data - Yahoo Finance

You could use data from other sources like website (e.g. ᐅ VANGUARD TOTAL STOCK MARKET ET Historische Kurse | Historische Werte | ARIVA.DE)

Thanks. Strangely enough, starting a new .xml file from scratch seems to resolve the issue. No idea why yahoo would return differently for the same ticker, other than maybe there are other parameters being passed.
