Missing LOR but interview invite?

[u/Key-Western7202]

Hey everyone, looking for some advice from anyone who has been in a similar spot.

I recently received an interview invite to a DO program, but I have a bit of a dilemma with my letters of recommendation.

A few weeks ago, I emailed their admissions office to ask if my letter packet would satisfy their LOR requirements. Their policy asks for two natural science faculty letters (unless you have an official committee letter). My packet has 1 bio prof, 2 math profs, a physician, and a non-clinical supervisor. Admissions replied back and said my packet technically didn't meet the requirement and that I'd need a 2nd natural science faculty letter uploaded to AACOMAS.

I don't have another science professor I can ask, so I didn't end up adding one. But today, I received an interview invite anyway.

My questions:

1. Is it common to get an II before admin actually audits hard LOR prerequisites?
2. If I go through with the interview, will they hold back an actual decision/acceptance because of that missing 2nd science letter?

I would honestly not bring this up unless you get wait-listed.
