Need help in Div Block setting!

Hi, I am working on a project and facing a weird issue. I created a number section on the website and separated them by a line (div block), but one of the lines is thick, and the other one is thin. Although both have the same settings.

Can anyone please explain why I am facing this issue and how I can fix it?

Thank you in advance.

Hey Imama,

Try this setting on the lines:

Might work, might not, difficult to say without your project linked!

This can also happen if the center div has a border on the right side, and the right div has a border on the left side. You would get a double border.
