Numbers appearing in controls when aligned right

Hi there,

I changed my controls so that they are right-aligned with the following CSS:

.nivo-controlNav {
    text-align: right;
}

but now i see the numbers appearing as well as the ‘dots’, and haven’t succesfully figured out how they appeared or what to change to hide them again.

Can anyone help me out? thanks so much!
