URGENT Sticky Menu text disappear and mobile Menu icon and text doesn´t show.

Dear MASTER author LEGEND,
Please Help me with this issue, www.terratest.cl

1. In Home, when the menu goes down to sticky, the text disappear or does not change to another color. Can´t solve this.
   This is NOT happening in the interior pages...

2. In Home Mobile, the menu icon is there, but it is white, so you can not see it.
   also in Mobile with the menu displayed, some text doesn´t show until you press it. please i´m dying!

i know it might be a little dumb detail, but i feel so lost right now!

I think i solve this...
