Formatting issue with Sanity causing text to be messed up on published website.

Hello, whom do I contact if I have issues with Sanity?

Basically, I am running into a formatting issue. Although everything looks perfect on the Sanity Studio, once I publish it on our website the formatting of the text is messed up.
Here’s the link to the website blog (formatting issue start at the 2nd half of the article):

I'm pretty confident formatting is not Sanity issue, but content issue.You have extra empty lines in the content itself

Yes, we have checked the content but found nothing. My frontend colleague said it could be a bug. But even if it is a content issue, what could it be?

I think it would be almost content issue.

you need to look into the way to parse content to frontend section.

Definitely. Although it’s not impossible to find an issue in Sanity’s portable text, it is very very unlikely and most likely a rendering issue on your side.

It was the headings issue. When I put all headings in the same format, it worked.
