editting pokemon in gts in hg

[paf]

I need a help. does anydoy know how to edit the pkm that you are going to receive after that screen of checking the gts's status in pokemon hg/ss? I had a problem while trading Poké Classic Network and now I cannot connect with my ss save there anymore for me to trading. that's why I'd like to erase the GTS data from my save.when I try to connect there I got the error msg in attachment. So is there a way to erase the GTS data from my sav?

Any help I' really appreciate it.
