The answer to your question...
Can someone please tell me the meaning of this?
...is "indeterminate". They, i.e., the VFS, is attempting to adopt something like the 'Amazon model' where the customer gets lots of updates about their order. They present six different status markers which would normally follow the sequence from top to bottom. The markers are "noob gibberish" which are either incomprehensible to the end user or require word-by-word scanning.
Incredible to relate, the strapline says "...returned description %s..."! Look at it in disbelief!
In your case, they show an illogical sequence with no explanation (and of course you came here for an answer and we'll do our best to help out). As I mentioned in comments, the my best guess is that the database person was out and somebody screwed it up.
Even if it were in sequence, those steps have little meaning to the end user, presumably "dmc" means "decision-making consulate", but what does it tell you? It's an amateur hack. Buggy.
What this amalgamates to is: indeterminate, ignore it, that system is not trustworthy. Your application is in the pipeline and you'll just have to brass it out.
