Walnut is acidic and some plants do not like acid soil. Western USA plants tend to like alkali because the deserts are alkali. Hydrangeas reversibly change color from pink to blue depending on soil acid or base.

Two things: first, while there is some juglone in leaves and nuts, it's the roots hat do nearly all the damage to other plants. There just isn't enough that survives decomposition or incorporation of the leaves into soil to be much of a problem. But the roots release it directly where it is absorbed by other plants, and as noted, for many species it is deadly. And, because roots spread much further than the crown of a tree, you really want to be far away - at least twice the crown spread - from a walnut if you're growing sensitive plants like solanaceas and rose family plants. It's also fairly persistent - it can take quite a few years for the area around a walnut stump to be clear enough of juglone to be friendly to those very sensitive plants.
Second, don't trust the lists completely. I've had yews growing under walnuts for decades, e.g., and I know from experience that some squash can be sensitive and that cucumbers definitely are. Grapes are highly variable - those with a fair amount of Europea (Vitus vinifera) being more sensitive, but North American (Vitus riparia and labrusca) handling things pretty well.
