The character that shows up in ur profile is the highest class that you have, but in this case you only have feeders, so it goes by the levels instead
so once you have reached more experience than that guardian your new character will pop up instead
Let's say if you mq the barb and pass to sammy, that will always show up there.
If you fail tho, u still need to reach lvl 58+ to make it visable again
edit#2
If you want you could save the guardian up at lvl 55+ just to keep it as a mule, sure might be a bit harder to find extra equipment slots for a guardian, but at least it's something
