Login prompting for more information

I am the admin of the office 365 subscription for our small company, we do not have 2FA turned on, nor is it desired.

Recently when attempting to login I am met with a screen stating 
"More information required

Use a different account"

When I click next, I see a screen

"This sends a text with a auth code to my cell phone" 

If I hit cancel, I am prompted with a screen requesting additional details with green checkboxes next to the information I've previously entered.

I've checked all the setting in the admin portal, and 2FA is not enabled.

I believe this is related to the fact that I had a microsoft account associated with my company email address before we switched over to office 365, as this issue only seems to effect those in my company who had a microsoft account previously.

Anyone know to disable this, or to remove those person accounts associated with our work emails?
