ReSharper (Ultimate) - Rename parameter showing incomplete suggestions

Not so long ago (1-2 months) I noticed difference in "Rename" parameter behavior

was: when I press down button in Name textbox it was showing few suggestions. For example, if parameter's name was someLongNameGoesHere it suggested me something like: "longNameGoesHere", "nameGoesHere" etc

now: only same name is showing, see screenshot below:
