I attempted to reproduce this (wiz3/cleric2) and was prevented from adding that feat. Do you perhaps have the trait Magical Knack or something else that is either boosting your caster level or granting you the ability to craft arms and armor ?
Can you provide the .por file ?

I think I've duplicated the issue:
Open HeroLab, start a fresh portfolio.
Give it 5 levels, first 3 wizard, then 2 cleric, but do nothing else.
Try to assign the Craft Magic Arms and Armor feat.
HL will complain you that you need CL 5 by showing that re-requisite in red.
Now go to the Background tab and assign a race (it doesn't seem to matter which).
Try to assign the Craft Magic Arms and Armor feat.
Now HL won't complain.
I'd say this is a bug that should be reported to Lone Wolf.
