Hi B_R, I noticed that too.. . .
Your actual Downloads folder is the one with the ID number:
{374DE290-123F-4565-9164-39C4925E467B}
The other folder seems to refer to Local Downloads - how that differs from the actual Downloads folder - strange . . .
Just in case you ever need it, here are the strings for the other mystery items:
{3B193882-D3AD-4EAB-965A-69829D1FB59F} Saved Pictures
{AB5FB87B-7CE2-4F83-915D-550846C9537B} Camera Roll
