How Do I remove the Slider Naviagation and Headers from Black Bird Pro V1.9.4

I am new to word press and this is my first theme I have found that looks they way I want. I would like ot know how to fix the slider to just show my 4 images. I dont want to see the slider naviagation or any wording just pictures changing.If it is not possible to remove the navigation, at least remove the big brown square box telling me to " Premium word press themes with single click installations" Thanks for your help and great products.

 

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.flex-caption {
display: none;}
 
.flex-control-nav {
display: none;}
@media only screen and (max-width: 767px){
.flex-control-nav {
display: none;}}
 
@media only screen and (max-width: 480px){
.flex-control-nav {
display: none;}}

 

thank you for the quick response and fix.
