Including middle name on Form1 SBR

I recently completed my first Form1 which was approved. On the form in box 3B my name is FIRST MIDDLE LAST. When I went to get my lower engraved however I only put “FIRST LAST CITY, STATE” Is not including my middle name a violation of the ATF’S engraving requirements? Idk if this matters but I am the only person with the first and last name in my city/state.

EDIT: If the way it is currently engraved is in violation, what would be the best way to correct it? Would I just need to engrave the full name, city and state in another part of the receiver, or do I need to etch over the current engraving and laser etch the correct one over it.

EDIT 2: I called the NFA branch and the man on the phone said “I’m not well versed in the regulation please check the website” on the ATF website I found the page that talks about marking the lower but nowhere does it say it must be your full name, just says name.
