org-shift[up/right/left/down] gives error on Org Clock Table pattern `yyyy-mm-dd`

Question

I am having an issue viewing my time logged for individual days. I want to easily traverse through each day, and view the Org Clock Table for that day. When my pointer is on the clock table's config row that starts with #+BEGIN, I can easily traverse through each week using org-shift[up/down/left/right]. For example, with my pointer on the line #+BEGIN: clocktable :scope tree :maxlevel 4 :block 2016-W01 :step day :link, I can press S-right to traverse to the next week by changing the :block 2016-W01 to :block 2016-W02, which updates my org clock for that week.

But org-shift does not work on the date pattern when it is defined for a specific day. For example, on the second Org Clock Table in my example below, I changed 2016-W01 to 2016-01-05, in an effort to traverse each day instead of each week. But now, org-shift[up/down/left/right] does not work. I want to easily move through my timesheet and traverse 2016-01-06, 2016-01-07, etc. but org-shift gives me the error: org-clocktable-shift: Wrong type argument: integerp, nil.

I investigated a little further, and I found that org-shift[up/down/left/right] works when I use the form [2016-01-06 Wed] for my :block (ie using the line #+BEGIN: clocktable :scope tree :maxlevel 4 :block [2016-01-05 Tue] :step day :link for my table below), but the Org Clock Table does not recognize that format. Is there a fix for this issue? Are others experiencing this same issue? Should I file a bug?

Or, is there an easier way to traverse daily Org Clock Table reports, via :step day?
