I have recently noticed two types of questions marked as duplicate, the both have [Duplicate] in the title, and they both have something like this at the bottom:

However the first one has this at the top:

And no extra automatically added code at the top if you go into Edit view. And the second has this at the top:

And Edit view reveals this added code at the top:

So my question is this, what is the difference between the two Duplicate marked questions? Why does one have one thing added at the top with supposedly automated code, and other a cleaner look? Is the second one the old system or something?

Is the second one the old system or something?

Yes.

In 2013, changes were made to "Close as duplicate". Presumably, the second question was closed before February 2013.
