Help! I can't figure out how to adjust the derailleur.

I swapped out my 2013 shifters and brake levers for the new 2017 combo set. Used new cables and installed the required new DR anchorage spring set. But I can't get the derailleur to shift properly. It wants to sit in high gear. I have to unscrew the adjuster at the shifter all the way out to get it to almost move to low gear. Any ideas?
