Default CG On E-Flite Extra 300 1.3m

OK. So I just finished build and holy crap! The CG is way aft when the battery is placed in the compartment in the position indicated by the instructions.
By moving the battery all the way forward against the engine compartment, I managed to achieve the CG indicated in the attached photo. This is still aft of the recommended CG by about 6 mm (see photo).
It makes me think I have done something wrong, but I've seen comments about achieving correct CG by moving the battery forward as I have.
I can get the CG in range by adding an additional 60 grams in the nose, but it seems like I shouldn't have to.
I'm wondering if anyone else who has built this plane has encountered the same issues, and how they were resolved.
BTW, my installed battery in photo is 225 gram 4S.
Thanks!

(Well, I can't post my photo because I don't have 10 posts yet LOL. Just assume a photo exists of my CG aft of recommended range by 6mm)
