It was a backup of a 6.3 and restore to 8 a few weeks ago. The license looks fine and has plenty of capacity. I've made tons of changes to it in the last few weeks. Last week I had an issue with the dup command working intermittently and a reset 4 was done. That seemed to alleviate, but now I can't add or dup w/o that 'duplicate entry' error. I can remove and change, but the other commands don't work. They are available for commands and I enter all the info of what I want to add, but after hitting enter that's what spits out. After removing, I run the list usage command and disp stat commands and the station I removed is not in the system. However, can't add it back or any other for that matter. Not that it mattered, but I went into SMGR and tried the element cut through and had the same issue.
