2 Recovery partitions

Hi,

I found out i got 2 recovery partitions

that's the output of diskutil list

/dev/disk0 (internal, physical):

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *128.0 GB disk0

1: EFI EFI 209.7 MB disk0s1

2: Apple_HFS Macintosh HD 126.5 GB disk0s2

3: Apple_Boot Recovery HD 650.0 MB disk0s3

4: Apple_HFS Recovery HD 650.0 MB disk0s4

/dev/disk1 (internal, physical):

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *500.1 GB disk1

1: EFI EFI 209.7 MB disk1s1

2: Microsoft Basic Data BOOTCAMP 40.0 GB disk1s2

3: Apple_HFS Dati 200.0 GB disk1s3

4: Apple_HFS TimeHD 259.5 GB disk1s4

How can i get rid of one of them?

Also...the Bootcamp partition is working fine, it boots regularly, but it won't appear in the boot disk preferences:
