I haven't assembled this cabinet yet.  I ran into problems at step 2.
The holes in the board labeled D do not match the picture in the instructions, therefore I cannot assemble it beyond this point. The O bracket in the I board does not line up with any holes in the D board.    Is there a misunderstanding with what I see in the diagram?  Your assistance would be appreciated.
Trying to figure out what to do at this point.
