[Bug] Mass Sorting changes Trainer Data

[Atrius97]

I'm having an issue with the latest version of PKHeX, (v200314 as of writing)

Holding Shift while sorting to mass sort all boxes seems to unintentionally change a number of Trainer Data values, drastically increasing the values: egg_hatching, capture_wild, total_capture, trade, and wild_pokemon_encountered.

I believe PKHeX is somehow treating sorting the boxes as brand new encounters (pokemon caught/encountered values) and also trades simultaneously, as I have performed no trades on this savefile, yet the "trades" value reached into the thousands after sorting a few times.

Update, 18/03/2020: 
It appears that virtually any use of the Batch Editor to modify Pokemon also triggers this issue.

I noticed (with help of others) that using the tool weridly changes bunch of values, setting them all to 65535..

This bug still continues to occur in newer versions of PKHeX as of 14/06/2020, in both Stable and Experimental Builds of PKHeX, I've opened a Github issue here reporting it: https://github.com/kwsch/PKHeX/issues/2859

Edit: Fixed here: https://github.com/kwsch/PKHeX/commit/8936c584173aacedbaac1734355a1eb2996d736e
Thank you Kurt
