Microsoft have changed where the recovery partition appears on drives now.
Originally it was put in the 1st partition space but on newer installs it now appears after the Windows partition.
The reason for change is that the 1st recovery drive isn't big enough to hold all the info needed for it to do its job, so they started creating multiple recovery partitions, on pre existing installs, so its quite common to have at least 2 of them.
On more recent installs they have moved it and you should only have one.
Recovery partition is special, most partitions can only grow in space if there is unallocated space on drive after it. Recovery can take space from both directions.
So its now created at end of drive and takes whatever it needs...
