Widget top line

Those lines look like they’re coming from your theme. Every widget you add has a class of “widget”. It’s possible that your theme has a style something like the following:

.widget {
    border-top: ...;
}

Great idea! I found a border-top in one of my theme files indd ??

Thx for suggesting this! ??

Edit: already found it ??

Awesome! Let me know if you need anything else.
