Question regarding name inconsistency

[Derek & Cece 27]

Hello there! I've been concerned about something recently and I was hoping I might get some reassurances here. My fiance is originally from Vietnam but has been living in Austrlia for the past 5 years as a permanent resident. She goes by Cece but her legal Vietnamese name is different. When I filled out my I-129F petition I used her legal name (obviously) putting her first name in the first name box, her two middle names in the middle name box, and last name in the last name box. Then put Cece in the other names box. So far so good.

Fast forward to today and as we are getting ready for our interview I realized that she had been writing her legal name differently since she moved to Australia. She has been using her middle name as part of her first name on all of her Australian documentation such as for work and stuff. Specifically, she has been writing her middle name in front of her first name. I'm worried that this might create some confusion as we prepare for our interview. Is this something she might be able to explain during the interview or is it possible we might get denied due to the inconsistency? I know that some cultures write their names in a different order compared to others, but I worry for things like the Australian Police Name Check is running her Middle Name+First Name, Last Name which isn't the same as how I have it written in my petition or how it might show up in her Vietnamese paperwork.

She can explain during the interview. The worst case scenario would be a long administrative process.

My guess is that it could cause a slight delay at most.
