Jerboa defaults to All / Old when I have my settings set to All / TopDay?

Any way this can be fixed in a future release? I've only done a little bit of coding in the past, but this sounds like an index matching error with a hopefully quick fix (i.e., specifying "TopDay" is supposed to return the Xth item in a list, but it's returning the X+1th item instead, hence the sort by old). As a result, Jerboa always shows me posts from four years ago when I open the app.
