POB defense platform position

[Lusitano]

Hey

i'm putting some defense platform on my pob because why not and never know, and i'm having some problems, and that is i can't move then. first ones not that bad position, just a big far .. not much ... from the base, but the seconds are in the merge with the first one! and every time i try to put in position, type all correctly from the /pos and what the guide says it say that is out of range, even if it is just 100m from the base! so ... any guess what is wrong?! also if the turrets are merge, will they fire like two turrest and not just one?

thank you in advance
