Problems with 'Set Translator Name' on a Source Model

I imported a source model using Remote XML file - http://www.w3schools.com/xml/plant_catalog.xml . So the translator in the source model is 'ws'.

1) Pick source model > Connection > Set Translator Name . In the dialog I entered 'idk' for the translator name. We should provide a dropdown of available translators if it is available, instead of text box.

2) after i set the translator to 'idk', I did Connection > View Connection Profile Info. The translator displayed is still 'ws' - not the new one that I set.
