Hi Chris,
Missing some details, so let me give you most likely things to look at.
1) Inspiron , which branch readiness config did you have, SAC or SAC-T. If SAC, then remember, we are adding +60 as a one time event, thus it will be 60 days
2) What did you configure for the Surface specifically, or did you mean its just default?
3) If a device is default, ( new device old device never changed, or has been restored) it is not the same as a deferral of "0". Instead, it is managed via the WU intelligent role out process, which is non-deterministic by device
4) If the device has a compat block, ie there is a known conflict not yet resolved, we will not update the device into the bad state, even at the deferral period. You can see the known and tracked issues/compat blocks on the release history page
