CTA section showing grey line at the bottom. How to get rid of it?

Hi everyone,

I’m creating a new landing page, and realised there’s this grey line at the side and bottom of the CTA section (seems like it’s in the Divider section)

It’s meant to look like below:

I’ve tried to change the Border setting within the divider - changing the colour from black to transparent, and changing the width to 0px, but that didn’t help with the issue.

If anyone know how to solve this issue, that will be greatly appreciated!

Many thanks!
