Thanks for reporting; the comparison skipped the move instead of only checking for that move.
Fixed in latest commit: https://github.com/kwsch/PKHeX/commit/2c4e3358e469caf322ac32a024e2d052892d2cf2#diff-f0296ad5dc139e277021748ee2f70145L582
I've updated the release with this hotfix
It's a .NET assembly; you can run it through ILSpy, .NET Reflector, or dotpeek to decompile.
A lot of the functionality was re-implemented in PKHeX... dunno what exactly you're looking to do
Pushed some changes, not sure what else is left to fix (I don't think I changed anything for saving the values...) Probably the seen&unseen case (is that even a possible ingame case?).
Thanks, fixed in latest commit:

(the Static Encounter IV checking is new as of yesterday)
Open a new Windows Explorer view (Windows Key + E), and enter "%TEMP%" (no quotes) into the search bar and press enter. You can probably delete all the files there (or maybe just run ccleaner or another cleaning utility). Basically pk3DS tries to get a temporary file location, but the random file it gets is already used (failing).
As usual, loading something to tabs and calling it to check legality will end up re saving the data, which includes updating the catch rate if it is atypical.
Check the legality from the box, don't load to tabs.
Normal cartridges always yield static encounters with Method 1. Emulators do not faithfully emulate, resulting in atypical PID methods.
Since these PIDIVs are not possible on regular cartridges, the pkm is not legal. Just because you emulate the game doesn't mean you're emulating it 100% accurately.
PKHeX is working as intended.
There is not a way to select by a pkm's typing, or to filter by {is any of the following values}.
You can always move them to a box manually, then filter for that box prior to running your modifications.
Nobody has done the research on how to edit that.
Can't just wave a magic wand to get something implemented.
Save editing research belongs in another subforum.
