CROSS_CONNECT_Z_SIDE incorrect Final A-side System Name

How can we get the correct Final A-Side System Name using the API as displayed in the Install Base Download for Metro-connects or inter-IBX cross-connects?

This is what we see when getting the asset details with the API https://api.equinix.com/v1/assets/

{
    "key": "SYSTEM_NAME",
    "value": "CH2:02155:EQUINIX",
    "tag": "A_SIDE_INFORMATION"
}

But when we download the Install Base we see that information displayed as the Legacy System Name in the Cross-connect Z-side report.
Final A-side System Name: CH1:05:XXXXXX:Some Other Broadband
Legacy System Name: CH2:02155:EQUINIX
