Solved Problem with the Section Dividers

Hello,

I have a strange problem with the section dividers. The dividers are only visible while the visual builder is enabled. Once i disable the visual builder or if i open the page on another device all the dividers are disappearing.
However all the dividers which i created 2 or 3 weeks ago are visible. But now if i try to create new divider it's not showing out of the visual builder.

 

Here is the link:

I found out that the dividers are not showing because the link to the image of the divider is wrong.
When i replace the wrong link with the correct one from console the divider is showing up.
I wonder how this can be fixed to generate the correct URL for the different dividers.

 

I changed the color and it is working fine! The color was set to white but for some reason the visual builder is showing it black.
Thank you!
