Alt + click clipping not working
Hi there, I have a problem with clipping layers.
I have tried to clip the "ADJ" folder to the "IMG" folder, this is something I normally do using Alt+Click between the two folders, when the little arrow facing down shows up. But now, when I click alt and my cursor is located between the two folders, the little arrow doesn't appear and I can't use the clipping function.

This happened suddenly, a few weeks ago I was doing it. What could have gone wrong?
Thank you in advance.
