Demetre I of Imereti confusion

[Paxter Redwyne]

Why is Demetre I of Imereti 63 years old in the game? Isn't he supposed to be younger brother of king Vakhtang IV as Developer Diary from 8th august suggests? https://forum.paradoxplaza.com/forum/index.php?threads/developer-diary-8th-of-august-2017.1038756/
I am confused who is he supposed to represent. There were two Demetre at that time. One is a duke of imereti and second was co-king of Georgia.

Can someone clarify to me this?
I searched forum and posted this question on few threads about Georgia but I haven't found any answers.

Apparently, those are two different persons whose fathers had same name.

The brother of Vakhtang was born in 1413, but Alexander of Imeriti died in 1389.

I already noticed that. My question is: Who Demetre in game is supposed to be? On Dev Diary they said that he is supposed to be Demetre, co-king of Georgia, but in game he is too old for that. If he is supposed to be Demetre, duke of Imereti, I think he should be vassal of Georgia, not independent ruler.

Demetre doesn't have a defined birth date so the one you see in game is randomly generated.

That being said, as per the dev diary, and the fact that Imereti in game is a Kingdom rank, then it's probably supposed to be the younger brother Demetre. But his starting ruling date is 1401, which is that of the Duke. While the ending ruling date is 1446 which is that of the King.

Can someone from Paradox look at this issue? @Trin Tragula maybe you can take a look at it?
