assetHistory adjusted prices problem

Hello,

I'm trying to load adjusted price history for SPY ETF but I unable to do this

Here is my code:
https://gist.github.com/alun/429a849b75812bea5e7253ed43fda9ed

after running both SPY.t6 and SPYuna.t6 have identical price charts (unadjusted)

FROM_YAHOO vs FROM_STOOQ makes no difference

Is this a bug or am I missing something?

As a workaround for now I managed to use DownloadEOD script which loads adjusted prices for me.
