Spoke to the fine folks at Lacuna who are the manufacturers of the meter.
The meter has six divisions, and if you are seeing "Option Deleted" you have somehow changed or switched to a different division.
Solution:
Turn meter on by pressing both arrows,
Immediately thereafter press red button plus arrow up (or red button plus arrow down),
Press red button (mode) until data set is restored.
