At any rate, it took a lot of forethought and patience, but I've upgraded to High Sierra and reformatted my internal SSD as APFS with one container comprising six volumes.
Congratulations on finally making the leap and just in time for the first beta release of MacOS 10.14!
RE: My issues with Disk Utility these screen shots submitted to Apple hopefully are self explanatory.
NOTE: The problems only happen when there is an APFS Volume involved. So far I have not been able to generate any issues with Mac OS Extended, FAT, or EXFAT volumes. I hve also found that as i continue to make changes without recycling Disk Utility the display and other glitches begin to cascade and grow. As long as I recycle after each operation there are no problems.
