Creating new weapon infocards, one infocard does not change

I turned all the EMP missiles into Capital Guns, (mounted as Cruise Disruptors) and while they work as intended and have the new names I gave them, the infocard for the weapon stays as the original EMP Missile infocard.

I did make sure the infocards I used were not in use, and
for the Eraser I used 300000 for the name and 300001 for the infocard.

Do I need to find a free space with specific numbers?
