Hi Leigh,
The plugin is theme dependent for css selector.

For your current theme, Please put this in bp-custom.php

function bpgclite_custom_selector( $selector ) {
	return 'body.is-single-group .site';
}
add_filter( 'bpgclite-css-selectors', 'bpgclite_custom_selector');

That will work. In future I will be thinking of giving site admin otpions to enter their selectors instead of writing code.

Please let me know if it work or not?

Thank you
Brajesh
