Hey @lazypitbull,
Thank you for reaching out to us for assistance. This is simply due to how the Instagram login system works. Please see our documentation here [link] about this. Likely, you will have to ‘remove’, meaning separate these from being logged into only through Facebook. After the ‘removal’ process from a single login, you will be able to log into the account using the account name, and the same password. They will both be connected to the same email, in the case that you need to perform a password reset. The removal process is described in Instagram’s Support page, here [link].
After doing this, log out of instagram.com, and next, you connect an account in our plugin you should then be able to select that you want to choose another account and log into the correct one.
Let me know should you need further guidance.
Best regards,
