How to change autofill ammo type on ammunition shelf?

[Golgo 13]

So I'm trying to set up an ammunition shelf next to a chaingun loader that mission starts filled with chaingun rounds.

I know that by default it fills with 2 coilgun boxes because of the ammoboxcontainer tag and that adding chaingunammosource will cause it to fill with a chaingun box (so 2 coilgun and 1 chaingun) however every time I try to remove ammoboxcontainer it just automatically comes back meaning that I'm forced to have 2/3 of the shelf full of useless ammo.

What am I doing wrong? or is it something that just can't be changed?

Hi! Just noticed this weird behavior. Could you solve it in anyway?

As far as I can tell this is either a bug or a development oversight.
For now you'll have to use a workaround by unchecking autofill and manually placing a couple of the correct ammo type in the shelf.
