I can't delete two spaces

I’m working with copied text from a web page that comes with two spaces between some words. I used the block “Replace all text”, but without success. Remembering that I always used this block and it always worked, but this copaid text from a web page is not working.

No way, certainly it will work…

this should work. and what kind of text if not a secret

Use Do it to debug your blocks… show us the Do it result before and after processing…
Also make sure there are 2 spaces in the segment socket and 1 space in the replacement socket
