After starting your free Partition Assistant Standard Edition 5.5, the firs thing I notice is that you are not displaying the partition labels for any non-NTFS, non-FAT32 partitions.
I am sorry for my late, as for your question, we are sorry that our Partition Assistant doesn't support to set and display partition labels for non-NTFS and non-FAT32 partitions. Sorry for any inconvenience.
If you have any other questions or suggestions, please feel free to let us know.
