Help about the "×" in data of the pokemon

[solid.snake.21]

I don´t know what means that () in the seed
The pokemon is legal, but i get it after HOURS (Plusle in Emerald). I have the same problem with a Nosepass

Hold control when requesting a legality report to get the verbose output. 

Refer to the change log for changes between PKHeX releases

24/03/10 - New Update:

Legality: Added Encounter Slot RNG correlation checks for Gen4 (and Gen3). Because Encounter Type PID mismatch wasn't enough!

Gen3 correlations are complicated by vblanks, so with PKHeX's default settings it does not raise a flag. Basically, the program tries to check the encounter conditions (if you need a specific lead), and indicates if it is unable to determine how that frame was encountered.
