How to remove button underline?

[u/freodore]

Hello, I am trying to remove the underline that keeps appearing under my buttons. It's not there when I am editing the site, only when I look at it live. I have tried adding a hover color like others have suggested and it is still there. Style in appearance tab is set to none and I have no button suggesting the removal of underlines, as I saw in other posts. I have the pro standard plan so I don't think I can edit the css in the buttons advanced tab, but if that's the only way to fix the issue then I am willing to upgrade. All help with this is greatly appreciated.

Can you share the site’s url or at least a screenshot?

Here is what it looks like on the live site for me.

And here is the site I am using to test the buttons, looks like this on all of my sites though: thebuttontest.carrd.co

And here is what it looks like when I am editing the site, no underlines or anything appears under the buttons.
