What does the (X) mean in the Origin seed? and How can I remove it?

[Crescent Hunter]

Every wild pokemon I got, which I modify. Their origin seed have the (x). But not for my other pokemon in static encounter such as gift pokemon (lapras, eevee, bulbasaur), legendary bird and mewtwo, pokemon from celadon game corner, and fossils.

What is that (x), how can I remove it?

It means it failed to validate the encounter slot RNG correlation, which likely means it's not legal. 

The severity of the check is currently Fishy for Gen3 as vblanks may cause it to be disjointed, but in 99% of cases it's a correct assessment.

How to remove it? Only assign PIDIV spreads that the encounter slot can have. Use a tool like Pokefinder to search.

Don't forget to change the met level. Different encoutner slots have different met levels, so you might enter the wrong met level that don't match up your PIDs and the X mark will always pop up.

legal only if you match all details, such as encounter slot.

When we talk about encounter slot, an example is to imagine a table with all the possible grass encounters for a route.
It is possible for the encounter slot for your PIDIV, relates to a different encounter (could also be different species).
