windows10, I've uninstalled simpleDNScrypt because it causes some problems with steam, but some files are still not completely uninstalled and now the proxies are stuck to my computer

I'm sorry if this is a stupid question, it's my first time here and I only have basic knowledge about internet

So when I uninstalled SimpleDNScrypt on settings, it says it has been uninstalled but when I check my drive where dnscrypt are downloaded, there's still some files left for ex : simplednscrypt.exe, uninstall.exe, bunch of words and numbers,dnscrypt-proxy.exe. three of the .exe didn't work when I click on it. I just delete all the files and empty recycle bin, but now I have this problem which is when I go to proxy settings, [I saw this](https://imgur.com/a/9CsLChK), the numbers and *.local are autofilled and when I delete and open the settings again, it autofills again. It causes my online games to never connect. I think that I didn't uninstalled simplednscrypt completely, if so then how can I uninstalled it completely? I don't have the files anymore since it's been deleted but the proxies are still there. When I go to safemode with networking, the proxy settings are no longer there, no longer greyed out, no longer refilled and everything came back to normal.
