Unable to match an encounter from origin Game when randomizing IV's

[Laotion13]

I'm using the encounter database to generate various pokemon from dynamax adventures, but for some reason, whenever I randomize the IV's or try to set Attack/Speed to 0, I get an "Unable to match an encounter from origin game" error. I don't make any other changes aside from editing the IV's

Here is something that comes generated from the encounter database

 

And then if I try to change Attack to 0

 

I don't make any changes to the PID or encryption constant, but notice that when I make it shiny (CTRL + Left Click), it's suddenly legal again, but there are some pokemon that I don't want shiny. I also noticed that the IV's are not randomly assigned and just stay the same when I generate from the encounter database no matter what pokemon I choose, the only thing that changes is the characteristic. Anyone have any idea what could be going on?

PID/IV correlation exists.

 Ahh okay. What could be causing the IV's to not randomize when regenerating the pokemon though?
I would go into the encounter database, search a pokemon (I'll use Reshiram again for the example)

Right click > View and I get this

 

I do that again and the only thing that changes is the characteristic, but the IV's are all the same still

Inside the program's settings for the encounter database you can use the main editor to provide criteria for the template generator. If you have a desired nature, gender, ability, etc, it'll try to match whatever is allowed.
