If it does enlean the AFRs by ~0.8ish after a couple pulls, then its definately your flash likely being set up for gas. Althoguh IMO it sounds like it already, but if you want to put a nail in the coffin.

Edit: before doing any of the above, post of log with fuel correction so we can see that the procede is actually applying no bias at all. I'll never reccomend intentionally going lean (0.8 above 11 is acceptable) but for any other people who find this post and think its acceptable, its generally not.
I was thinking of doing just that. So I could get more logs to send in and show there is a problem.

I checked the correction and I am pretty sure it was flat with no correction. I will double check again before any new changes.
