Even if, as they were, joining the V-Nav (FMC calculated glidepath) from above the initial MCP Alt window should have had 4000' until 12D when 3000' would have been entered until 9D and so on.
The FMC should be an aid, with the MCP Alt window still protecting the the crew from the "embarrassment" of FMC mistakes..
