Search form button text odd on update to 4

I have updated client site and have used fulltextsearch which is working fine just the search button which used to say go now says L for some reason and I cannot figure out why. Any ideas?

Maybe it’s using an icon font and the L is supposed to be replaced with a search icon? There might be a css class on the button that gives a clue.

Can you find the “FormAction” relating to the search form - if so, you can do something like

$formAction->setTitle('GO');
