It is a little difficult to judge this particular problem when you redact part of the text from the comparison checkpoint.
In general, note that it is possible to edit your keyword property checkpoint in such a way that you are actually adding carriage return and line feed characters in the comparison text.
Try converting your KeywordTest into a script and look at what you're using for the comparison text in the Property checkpoint.
With text comparison we find it useful to use aqString.Trim on both strings. This avoids the issue that Joseph is talking about. You'll have to create your own comparison instead of using a checkpoint, but you'll get the correct result.
