Have almost the same problem with ccleaner cloud's defraggler with some more detail.
This laptop was originally installed with windows 8 and upgraded to windows 10. The laptop had a regular HDD at first but I cloned and replaced the drive with SSD.
when I noticed that the cloud defraggler saw the dirive as HDD i checked from windows. Windows also saw the disk as HDD. I ran "winsat formal" as suggested by one other windows forum. This fixed the problem on windows defragmenter and the ssd is now seen as ssd. However cloud-defraggler still sees the drive as HDD. I tried to uninstall the cloud-agent and remove the computer from cloud-dashboard. Reinstalled the agent and nothing changed. The SSD is still shown as HDD.
Could there be a bug in the code which assumes that the original system disk is *the* system disk. many times when you use registry or wmi with programming library you get a list of entries and maybe the code assumes only a single entry exists and takes only the oldest one from the list (history) of system disks?
sorry for my english, not a native english speaking person
