QA checker for non breaking space not working

Question

Dear all, 
 I am using trados studio 2022 sr2 
 I am trying to get the QA checker to point ot when in source there is a Non breaking space but not in target, I have found this article 
 https://gateway.rws.com/csm?sys_kb_id=f226e6ec1b4b9a50772c0dcad34bcb51&id=kb_article_view&sysparm_rank=1&sysparm_tsqueryId=33d71ed68384aa14a6b1fab8beaad3e3 
 but I still get no errors also, i am surprised the regular tag checker is not poining out the absece of spacing next to the tags. 
 below you see an example of the segemnts i need the QA to identify

these are my settings: 
 
 you cannot see the space but i used the suggested alt + 0160 in source and target 
 and these are the tag checks

Has anyone encountered this issue, i am probably missing something here... 
 
 Many thanks 
 
 Rita

 Where did you configure this? In File -> Options?

Hey Rita, 
 I ran into the same issue today! 
 It looks like the regex doesn&rsquo;t work when added to an existing project, but if you save it in a project template first and then create a new project, it works fine. (Does not make much sense to have to create a new project to add a quality check, though.) 
 Hope that helps! 
 Best regards, Corinna
