Discord App Switiching my Account

I just got my Windows re-installed and i downloaded Discord. I have 2 accounts, one i use on the App, the other in google chrome. Althought when i opened discord the first time it didn't ask me for a email or password it just automatically opened my account i use on Google, and when i turned on my PC again this morning it switched from my 2nd to my 1st account.
Why. . . . .
