Hi Pilafa,

To remove the digit in the controller dots you have to set the same color for digit too.
Go to Appearance -> Theme Options -> Design Options Tab -> Custom CSS paste the following CSS code and Click on save all changes button:

#controllers a {
background-color: #404040;
color: #404040;
}

About slider issue please provide us the temporary username and password of your WordPress admin site via Email so that we can have a look into your issue.

Thank you!
