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

 You may be adding that regex rule in the wrong place. Apart from the difference between File>Options and Projects Settings , there are 2 places where you can add regex rules to Projects Settings : 
 
 and in the specific language combination: 
 
 The second place takes precedence over the first one, so if there is something in the second place, the new regex rules added to the first one will be just ignored. That maybe the reason why it&rsquo;s not working for you. you can quickly check my point if you add a rule to find the letter 'a' in target, a very common letter, to the same place you added the non-breaking space rule. Does it work? If the new rule doesn&rsquo;t work, you may try to add the rule to the second position&hellip;
