Rebranding - URL on sign out

Rebranding - URL on sign out

I have my company URL set for clicking on the image and on sign out - under the rebranding option.
 
When one clicks on my logo image, it works fine and goes to my website. http://...
 
However, when one signes out, it tries to go to my website using https://.  My app is set to be secure, but I do not want it to forward using https.  Would you please address this. 
 
Thank you.
