Somebody suggested I make a separate post out of this, thanks again for the answers in the other one. So how to avoid being rejected like many others have been, apparently, because of wrong name entry?

Caveat in my case; I happen to have a PhD and there are some funny countries like the one I'm from where this can be put into the passport.

At first I thought it was a good idea, and probably helps at some border checkpoints. However, it is much more trouble than it is worth, esp with regards to air travel, I'll spare you the details. So pictured below are the relevant excerpts name, plus the MRZ. However, the MRZ appears to be somewhat random, also shown the MRZ of my last passport where it is the other way around. Any tips welcome. Thank you.
