Facebook Login asks for a password on available active FB session

We use:

Joomla 3.7
JFB Connect Version: 7.2.0

Website front end: www.targetmytravel.com

Description of the issue:

When we have active Facebook session and we click on SC Login module > button Facebook, the website is asking for a password. When we click cancel on the prompt for password (without entering a password) the login works (see the screenshot
snag.gy/Re0m5Y.jpg). We checked User map section and for this user we see the icon for Facebook - the user map is correct.

We compared the JFB Connect settings to another website JFB Connect settings. They are absolutely the same but on targetmytravel.com site we have this issue. On the other website login works without asking for a password.

How can we have login with Facebook without prompt for password?

Thank you pointing e out to the possible problem. The Force Web OAuth Reauthentication was set to YES even though I have never changed it which is strange. Somehow it reset itself. Now when it is set to NO the log in is not asking for password re-entry.
