With PetTracker turned off -- seeing the default operation of WoW 7.2.0.23937 (updated 4/18/2017) -- going to WoW's main map (clicking "M"), and clicking the main map's hourglass (on the top right), while looking at any Broken Isles' zone, the hourglass drop-down shows you options for which world quests are visible. The bottom half of those options has a title of "World Quest Rewards"... for example letting me uncheck Order Resources, Artifact Power, Profession Materials, and Gold... to only show Equipment world quests, if I want.

But with PetTracker 7.1.4 turned on, and WoW's UI reloaded, that bottom half of the world quest controls does not show: there is no title of "World Quest Rewards", and none of the options that I listed above, in my example, are shown.

I second this. It took me forever to figure out why I had so few world quests on the map until I figured out those options were hidden and I couldn't unfilter the world quests. Turning off PetTracker returns the filtering options.
