Adjustment of Status - I-485

My wife and I have applied for my i-485, i-765, i-130 & i-131. on mid October this year. My wife is a US citizen and we just had our one year anniversary.I got done with the bio metrics on Dec first week, and that's the last update that's been posted on case status. While I have a couple of questions that bothers us and seeking wisdom here.

I came here on F-1 as a student about 5 years ago, graduated my Masters, started work and as a STEM student I got my EAD for one year which got extended to 24 months after the first year ( Had to apply for STEM OPT extension). My extended EAD ends on Feb 2020. When I had applied for my extension, I was at a different job and 2 months later I switched jobs and started work at a different company. I have been at my current job for about 1.5 years now. I have just come to realize that I was supposed to have reported a job change or change in company, which I didn't. I started the other job when we were engaged and I thought I wasn't gonna extend the OPT any further anyways, and so was careless with the reporting. I'm still on my F1 as I have just applied for my AOS.
My worries are

1. Will this impact my case on the i-765 application and will it be considered as an unauthorized employment, despite me working with my EAD and having filed my W-2 from my current work for last year.

2. Would this be a problem on my AOS and will this be brought up at the interview and if so, how do I go about it.

I'm not sure about the intensity of that mistake and don't know if it's considered an unauthorized employment. It has been bothering the hell out us ever since we came to find out that I should be reporting a job switch as well. Please advice TIA.
