Thank you, rolling back did work. Cheers.
FYI this code has worked:
.is-form-id-1794 > label > span {display: none!important;}
but I had to put it in a CSS file (Custom CSS in plugin Settings did not apply)
Ivory search > Settings > Custom CSS

Unfortunately it does not work, even with “!important”
