Blocks not showing after adding in Footer section

Hello coders and designers,

I am facing a mysterious problem. When I add a block to the footer section, it becomes invisible.

You can see the outer edges of the block elements but it doesn’t show up.

If I add the same block to some other section, it shows up.

The same happens if I add the footer menu to the footer section. It goes invisible again.

The theme is Refresh 14.0

Request for providing me some help or direction.

Regards,

Raj
