Okay, looking at the ones you marked, I think I see the confusion
So if Deoxys text has a 42 in it, like the one you marked here
(4?)2Qw8t e12jk1m88es5f5o xjm9m2 dg u7vt48srk.
You'd ignore the 4 since the 2 immediatly overwrites it.
When I'm writing dialogue for Deoxys, I use a random number roller that I programmed to decide what numbers she uses and how long until the next number shows up
So it'll pick 1-9 then 0-4, if the second roll is a 0 then that's how I get two numbers showing up in a row, sometimes it's two valid numbers, somtimes they're both ignored, it's all up to chance
