You could download a plugin like this: http://wordpress.org/extend/plugins/safecss/ and add these lines of css to your style sheet, or If you have a created a child theme, you can just add these lines to your style.css file
`.field-visibility-settings-toggle {
display:none;
}
.field-visibility-settings-notoggle {
display:none;
}`
mrjarbenne thank you so much . . pasting the about mentioned lines in style.css works . .
It doesn’t seem to work for me. Does it matter what theme you have installed on buddypress?
Your theme should’t matter. And no need for a plugin. Just make sure you add this code to your style.css and you should be good to go! 
.field-visibility-settings-toggle {
display:none;
}
.field-visibility-settings-notoggle {
display:none;
}
Can anyone help me? I tried to add this code to my functions php and got a parse error on save. i removed it and it’s still giving me a parse error;-( my site seems to be broken, now. I’m going to keep looking, but plz jump in if u can help. thanks!
Parse error: syntax error, unexpected ‘.’ in /home/massagem/public_html/wp-content/plugins/buddypress/bp-themes/bp-default/functions.php on line 39
Can i check how you resolved this, do i add the code above to the bottom on the public_html/wp-content/plugins/buddypress/bp-themes/bp-default/functions.php file or which one ?
Add the code to your style.css in your default theme..
public_html/wp-content/themes/YOUR_THEME/style.css
