Hi Etrenoir,

I just visited your Contact page and I can't see any problem on this moment.

See video: https://d.pr/v/P8Oo6B

Anyway, if you want them gray, then you please just add this CSS code to your Custom CSS area:

.labeled-input-row label, .labeled-textarea-row label {
    border-bottom-color: #ccc !important;
}

Have a nice day!
