This one was a bit difficult to find. And I didn't actually find the cause.
Somewhere in the code, the AI is getting hung up on discontinuing designs and not removing the design from manufacturing. I checked every place in the game where it can discontinue a design and made sure there was code to remove it from manufacturing, but alas, it was all correct. No issues found.
Anyway, I do have a checker function that runs every turn for removing a player design from manufacturing and sales and reserves when the vehicle is discontinued and you run out of reserves. (Like when you're selling through inventory after discontinuing a design.) I have expanded this function to check AI designs and any discontinued vehicles in manufacturing without reserves. It's a hack fix, but it's a fix.
In your case, it will take 2 turns to cycle through and remove it from the listings. In the future, this edge case shouldn't reach the player.

good human beings save the world, so that bastards like me can keep creating art, become immortal.
