In-game trades from generation 1 missing OT when transferred

[Twispan]

I've just transferred a few of the trade Pokemon obtained in Blue to Emerald, and when I checked their summaries they appeared to have no OT listed, although they still had Trainer IDS. I thought this was too frivolous of an issue to report but it does seem to be consistent enough to warrant bringing it up. I have no idea as to what could be causing this, Pokemon obtained from outside OTS via trading went through just fine, it's only these ones that had an issue.

Here's the save file from Emerald if that helps. The boxes are in National Dex order so it shouldn't be hard to find the afflicted Pokemon.

I do not entirely know if this extends to in-game trades from generation 2 as I have not done any of them.

Thank you for sending this my way- and sorry you're having so many issues! I did some research, and apparently all the in game trades in Gen 1 have the OT of the traded Pokemon as an escape character "0x5D", which prints as "TRAINER". However, since I have my text remove all the escape characters, that's where the blank name comes from. I'll have to check for that in a future release- thank you! I had no idea that was even a thing, the more you know haha

Interestingly, Transporter changes the name based on if it is coming from Gen 1 or Gen 2, despite both reading as "TRAINER" to my knowledge: https://bulbapedia.bulbagarden.net/wiki/Pok%C3%A9_Transporter#Pok%C3%A9mon_from_in-game_trades
