Discretization problem

I added a discretization with 4 classes, then wanted to add a 5th one, and it didn't work.
<operator activated="true" class="discretize_by_user_specification" compatibility="5.1.011" expanded="true" height="94" name="Discretize" width="90" x="346" y="93">
<parameter key="attribute_filter_type" value="single"/>
<parameter key="attribute" value="log_return"/>
<list key="classes">
<parameter key="E strong sell" value="-0.01"/>
<parameter key="D sell" value="-0.005"/>
<parameter key="C neutral" value="0.005"/>
<parameter key="B buy" value="0.01"/>
</list>
</operator>
I'm missing "A strong buy" obviously.
Then I resigned and just tried to change "B buy" such that the value is 1.0 rather than 0.01 but the change does not get preserved or saved.
Should I file a bug report? As I'm new to the tool, maybe I'm missing something obvious. Btw. RM is up-to-date as of now.
I also find that on several occasions in general, when I change something and want to save the results, the save button is inactive, as if it didn't register the change, or in other words, didn't update the "saved"-ness status. Is it a common and well-known experience?

Hello,

Thank you Andrew, you are on a roll, indeed the ordering caused the problem! The doc didn't specify the order and I didn't play around with that (actually I ordered it in the way natural to me, i.e. lowest to highest, and it didn't work).
Next time I bump into something, I'll search your site 1st :-)
