Endnote X9 Keyword cleanup

Hi! I am having some problems cleaning up old keywords from a large library:

I have keywords separated by a carriage return as this:

#keyword1

#keyword2

#keyword3

I want to get rid of #keyword2 from all the references that have it, so I tried with Find & Replace. However, what I ended up with was with:

#keyword1

#keyword3

what am I doing wrong? Is it possible to do this kind of cleanups when a keyword is not useful anymore?

thanks!

If you search for #keyword(insert special character, carriage return) and make sure there is nothing in the “replace with” box (go in to the box, select all, and there is usually a space there, and hit delete.  I don’t see a left over carriage return in the list.
