missing user login icon and question about moving home folder

i am having two weird issues where my user icon does not show up on a restart because it keeps disappearing after i see it for some time. also, i have moved my home folder from my "os drive" (DRIVE #1) to my "documents drive" (DRIVE #2) and i think i sometimes see the DRIVE 1 listed when i select something on my desktop.

for instance i was experimenting with Graphic Converter today and after selecting a bunch of images from a folder on my desktop it appeared to show that these were located on DRIVE 1 instead of DRIVE 2 where they should be located.

since i am only backing up DRIVE 2 (my data) this is a really important issue for me.

i have a screenshot of the OS drive (drive 1) here and am wondering if there are any other insights on how to test this fully and/or making sure something weird is not going on.

TIA for any help
