DOT Hours of Service Rules

So in the past, I was on my 14 hour clock and I went off duty for 2 consecutive hours or 3 consecutive hours I actually got the time back that I lost due to inactivity because of a vehicle defect. But now as of May 2023 I noticed that my clock is not being reset even though I've been off duty for over 3 hours and 40 minutes. I still have 6 hours and 46 minutes left on my drive line but it did not give me back my on duty time which I had when I got to this facility in Virginia Which at the time was 8 hours plus

Do you have too take your 30 mins break if you haven't drove 8 hours ?
