Signatures not showing up in posts

i don't know if it's just something i'm doing wrong on my end but my signature's aren't showing up on the bottom of my posts for any of my characters. 

when i make a new post or edit an existing one the "include your signature" box is checked. When I go to "edit signature" in my UCP, i have tried to select "enable my signature in all of my existing posts" and hitting "update signature" but it doesn't fix anything. 

not sure what else to try or if maybe it's a bug.
