Underbody damage not showing in MFD

I tested it again with a brand new career at the same track and everything. The only things that were possibly different were the starting order behind p5 (otherwise was the same) and the fact that damage is now off. Everything else, setup, track, difficulty, assists, etc. were exactly the same, even upgrades. Like the race with damage on, I came into the pits 4 seconds ahead of p2. However, this time around I still lapped the same or slightly quicker than the AI for the rest of the race, similar to the quick race I did yesterday. Instead of finishing behind p1 by 8 seconds like I did with damage on (no indication of damage in MFD or from engineer), I finished 8 seconds AHEAD of p2. Depending on how you look at it that's a 16 second pace difference and when pitting on lap 8 of an 18 lap race, that's a 1.6 second pace difference per lap (roughly). Also, the car felt so much better in the second stint without damage on than it did with sim damage. Everything here points toward damage except the MFD and engineer. There was also a similar post to mine made last year for F1 22 with the exact same issue. All of this indicates problems with damage showing up/ being reported, at least underbody damage.
