In a combination each entry takes two parts

   1. The content of the cell and
   2. the caption for the cell (unless you enable auto numbering)

but you're omitting the caption for all of them. While I say you omit 
the caption this isn't the actual truth because the \startcontent and 
\startcaption commands are just named alternatives for the braces which 
means every second figure in your example is used as caption for the 
previous image.

To fix your example add

   context.startcaption()
   context.stopcaption()

after the content for each combination cell.
