Unable to change backround image on row separator type A and B

I’m trying to add a background image on the row separator A AND B widget,after selecting the image when I click on done and when I save and publish the page , the image is not reflecting on my website.I downloaded all the settings and I’ve added services as suggested in the documentation, however I’m unable to add a background image to the separator widget. I’m trying to complete my website in a short duration any help with this issue will be much appreciated.

Hello there,

So sorry for the delayed respond. There is no way to do so, I am afraid.
