Previous deleted text keyboard shortcuts keep appearing I kept a bunch of keyboard shortcuts via System Preferences > Keyboard > Keyboard Shortcuts and over time, I deleted some shortcuts that are not necessary for me and added new ones.  

Some time ago, it appears that the unwanted shortcuts appeared back when the added one didn’t appear — manually deleting them in the system panel only made them return.  

How do I keep one set of keyboard shortcuts please?
Deleting from all devices does not appear to permanently fix the problem.  They live in the cloud somewhere, and I was told by Apple in 7/15 that the are working on a permanent fix.  Mine stay away from the most part, but have come back occasionally on my MacBook and iPad.
