In between the "ZOO"s that little springy thing, try and push it towards the top, any way you can make that happen ougta be fine.
Also, if it actually is aligned and that doesn't help (it's a little hard for me to see in this pic) it could just be gunky in the back of the assembly. If that is the case spraying an oil like Ballistol in the cracks and wiggling it may help.
