Applied at Subway for Shift Leader

Tomorrow, I have a job interview at Subway for a shift leader position. I'm facing a dilemma regarding my resume and what to say about my previous job. I worked as a supervisor at Ballorig but was let go after just three months due to being late with submitting my VOG. My resume hasn't been updated in months, so it still shows Ballorig as an ongoing position with outdated information. Initially, I thought about lying and saying I worked there for 5 or 6 months and left two months ago because the work environment didn't suit me. I figured that having 5 or 6 months of supervisory experience would look better than just 3 months and would explain why I'm only applying for jobs now. However, I'm worried that if I tell the truth, it might be a huge red flag, especially since I've been unemployed for a while and the reason for my dismissal isn't great. I'm also curious if Subway conducts reference checks for the shift leader role.
