Punctuation, verification don't work for unbreakable spaces

Question

I am translating a document from French to English using Trados studio 2019. Varification or punctuations don't work. 
 My document has some unbreakable spaces. 
 I have modified the settings for the current project as show in the screenshots. 
 
 Check for unintentional spaces before: 
 
 But spaces are not retained in the translated text as show in the screenshot. 
 
 Thanks, 
 Kaivalya

 When you attach a whole screen of text it is a help if you tell us where the undesired behavior shows... I guess it's the semicolons in segment 16 and following. 
 From what I can see, everything is working as should. There is a space in the source text, as should be in French, and there is no space before the semicolon in the target text, as should be in English. No QR issue is reported, because the English target text follows English punctuation rules. 
 I am not quite sure where the problem is.
