I lost my ranked records too and instead of resetting they changed completely.
While it is an annoyance by itself, I'm not really worried by it.
There's nothing you can do about it, it won't correct itself most likely (been like 4 days now it didn't for me at least)
I know it sucks when your stuff gets reset, especially if you like having a good record.
However I noticed W/L rarely means anything.
I've encountered people with 100's of wins and minimal losses, and won quite easily, cause it ended up that they just play cheap AF and since you encounter so many new players on a daily basis, they can not deal with your cheapskate tactics.
Most of the wins I got were from people that are new or have terrible w/l ratios for whatever reason.
More often than not do you fight people who can't grasp the game mechanics (yet) so wins like that are easy.
But in the end, due to that don't mean jack.
I made a topic myself about my w/l wipe, though while annoyed in the end I stopped caring.
There were people who assumed I was salty because of my ranked data wipe so to speak, but it was more about me thinking "WTF just happened? this shouldn't even happen!", I was annoyed by the issue on itself, not the numbers.
All in all, nothing you can do but move on.
