'replace' doesn't run in Visual Studio code

environment: Visual Studio Code (VSC), Extension: CQsearch codeque installed
I'm new to 'codeque'. 
In VSC I'm able to run 'Find', However when I use 'replace':
I always get a msg like " subscribe 17€ ... to early bird ...". I even went through that procedure; no success!

Can anybody tell me how I make 'codeque' working in VSC? 
thanks, ed
