Wonder Card legality checking help PKhex

[SUNandMoon]

So, I get a Shiny Xerneas and Jirachi based from the event that happened recently. However, PKHex flagged those two Pokemon as illegal because it is being said that I don't have the valid wonder card. and I don't really understand on doing a legality checking on PKhex for wonder card stuffs. Help is greatly appreciated. Thank you.

3/19/16 - New Update

- Added: Wondercard database loading for updated Legality checking.

- - Create a "wc6" folder in the same folder as PKHeX.exe, and add in wc6 files.

PKHeX only includes user contributed data; it can't know what events in the future will be legal. Everything is checked locally, so you have to expand the database if you want to check for new events. Either you do the above, or recompile, or wait until the next release (in a day or two) for the internal database to be updated.
