YouTube Restricted Mode

Question

I've managed to turn on YouTube Restricted Mode ... I think by checking the option to have Google Safesearch on. But YouTube Restricted mode is way too restrictive, so want to turn it off. 
 I've unchecked the Google Safesearch but web browsers still show YouTube Restricted Mode as on. 
 How do I turn it off? 
 Also, can I keep YouTube Restricted Mode as OFF but Google SafeSearch as ON? 
 
 Thanks

I eventually found out what this was. 
 Basically, in Sophos UTM there was an option to turn on YouTube Safe mode, which I had done previously. 
 I then upgraded to later versions, and the option to set YouTube Safe mode was deprecated, so I couldn't turn it off, in those later versions. 
 In the end, I had to rebuild from scratch and redo all the config again. 
 Was time consuming but worked.
