lipid Cer question

I've noticed something strange happen for certain Cer lipids using the built in lipid msp.  A ceramide is originally listed as Cer 68:5|(side chain info).  After I go into the peak spot viewer and select the "A confidence" for the exact same side chain information listed on the main page of the GUI, the name on the main page in now listed as Cer 68:6|(side chain info).  The combined chain length increased by one even though the selected side chain information is the same.  This also seems to happen to when I select a different side chain that adds up the same amount.  I'm using version 4.48.  I've attached two images as an example of what I'm seeing.
