Loading multiple paths as a selection excludes overlaps - which I don't want
I have a bunch of separate closed paths (each on its own layer) -- some of which overlap each other. My goal is to cmd-select them all (in the paths menu) and to then click on the "load path as a selection" icon, and to have the selection be the union of all the paths' areas. This works fine, except for with one particular path. If I include this particular path's layer in my alt-selections and then click "load path as a selection," the resulting selection excludes any overlap with this particular layer. This seems to be an issue only with one particular path layer! All other paths create a selection of the full union of their areas, which is exactly what I want.
I get the same behavior (the excluded overlap) if I click on "fill path with foreground color": any overlap with this particular paths's area doesn't get filled.
It seems like there's something "different" about this particular path layer, but I can't figure out what it is. Any ideas?
(A work-around is to individually cmd-shift click on each path's thumbnail. This gets a union. But I'd much prefer to be able to cmd-select all the layers, and get a union selection from a single click on the "load path as a selection" icon.)
Many thanks!
