Cannot drag-select layers with Move tool in Photoshop when initially clicking in the canvas

When using the Move tool, I can no longer drag-select layers when my cursor initially clicks on the canvas. However, if I initially click outside of the canvas I can drag-select towards the canvas, a rectangular marquee will appear, and the border to that rectangle successfully selects the layers it touches.

But, when I open a new document I can drag-select with the Move tool no problem.

Any ideas on what's going on? I reset all my tools, restarted Photoshop, and my computer. Still no dice
