missing available disk space - after drive upgrade
This doesn't seem right... our NAS currently has the following drives 6TB+4TB+4TB+4TB+3TB+2TB = 23TB OS 6.2.1 RN716X RAID-5 with X-RAID2 but the available storage is only 14TB - so we are miss...

The nas needs to create redundant space, it can't use a small drive to create redundant space for a raid array that is using bigger drives. Effectively you have a raid 5 array of 6x2tb, a raid 5 array of 5x1tb, and a raid 5 array of 4x1tb. The remaining 2 tb of the 6 tb disk is not being used as the nas cannot create redundant space.
