CRM 2022 R1 Advanced FInd - Not Showing Preview SQL Button

Good morning all, 

We are operating off Sage CRM 2022 R1 and the guide from https://help.sagecrm.com/on_premise/en/2022R1/Main%20Menu/Content/User/FI_UsingAdvancedFind.htm?Highlight=Advanced%20Find shows a Preview SQL button in Advanced Find but this does not appear in our CRM. 

Has anyone encountered this before or know where I might look to turn it back on?

Many thanks,

Paul
