All friends show as same profile background in new client

I'm not sure if this will replicate but I used practice tool, and after getting out of it everyone on my friends list now has my equipped profile background (TPA Shen). Not a huge deal but it's odd. I tried restarting the client, and it fixed it for people who were online the last time client was open, but it's still TPA Shen for people who where offline, and are now online, or are still offline.
