Replace Missing Values

Hi,
I'll just ask on how to use the "Replace Missing Values" operator. After the Apply Model operator, I am dropping some predictions using "Drop Uncertain Predictions" leading to a "?" value on the prediction(class) attribute.
What I want to do is change this "?" to a different string. What I've done so far, which unfortunately is not working is the ff:
1. Use Replace Missing Values operator
2. Set the attribute filter type to "single"
3. On the attribute field, I inputted "prediction(class)"
4. I ticked the "include special attributes" check box
5. On the default field, i selected "none". I also tried "zero" and "value". But none of them work as I expected
6. Edit the columns field and place prediction(calss) and value on the "attribute" and "replace with fields", respectively.
7. Under replinishment value, i placed there the string that will changed the "?" value. (e.g. "vague")
How should I do this? Your ideas are greatly appreciated.
Thank you!

Apparently this bug was fixed... see here http://rapid-i.com/rapidforum/index.php/topic,4653.msg16823.html#msg16823
But it still appears on my 5.2.
At least it is in hand.
according to the post by Marco he has fixed the bug shortly after the release of 5.2. Thus it is not yet contained in the current 5.2 release but it should be fixed with the next bugfix release.
Best,
Nils
But is this the root cause? I mean, based on my explanation/step by step description, haven't I committed some errors?
Thanks!
Greetings Nils
