Social Connection are following Administrator login - BUG

Hi guys,
PHP 7.3.22 + Joomla 3.9.21 + JFBConnect 8.4.6 - on Ubuntu 16.04 and last 85.0.4183.121 (64 bit) Chrome browser

I was testing the Social Registration, so:
- Joomla Backend - I logged into my administrator panel
- Joomla Frontend - Not logged
- I clicked on Facebook icon > JFBConnect connected my Facebook account (I was logged in Facebook with Chrome) to my Joomla Backend Super User account
- I clicked on Google icon > JFBConnect connected my Google account (I was logged in Google with Chrome) to my Joomla Backend Super User account

Expected behaviour: JFBConnect do not see me as logged, nobody has logged in Frontend > JFBConnect should have shown the Social registration page.
JFBConnect should never follow the Joomla Backend Login/Logout, but always and only the Frontend Login/Logout.

Am I missing anything ?
Please, Can you replicate it ? And in case fix it...

Hi Melissa,

A - "Does the email address on the super administrator account match the emails for the Facebook and Google accounts?..." = No, they are two different emails.

B - "...Can you reproduce the behaviour?" = I haven't tested it yet because I hate to delete/duplicate records on my live site. The User Map Linking should works also on a copy site (another domain) without any issue, Am I right ? If so I'll create a perfect copy of the live site where we can thoroughly do any tests...
