Odd Arm Posing?

For some reason when I stand up straight and rest my arms straight down, my arms do this (See image). They dont move straight down like they do irl. Does anyone know what might cause this? My base stations are in full view of me as well and this happens with every avatar I use, even in game ones.

This is usually because the arms on your character are too long.

So every avatar I’ve ever used has had too long arms?
