Not able to add condition for "Choice" column in Conditional Branch activity

Hi,

In my custom list, I have one choice column name "Status" and values for it are Active and Inactive.

In my Conditional Branch activity, I want to add condition for it i.e. Status equals Active

but value text box is not appearing for that. See attached screen shot to get more detail. It's something like

When -> List Lookup

              Source : Current Item

              Field     : Status

              equal

so here after equal, Value textbox is not appering. which appears for other type of column like Single Line of Text. So am i missing something in this or some issue is there from Nintex side with Choice column? Can you please suggest.
