Workout somehow deleted from PM5?

[robhely]

I just finished an intervals workout on the C2 erg and while toggling the "units" button I think I may have accidentally also hit the "display" button, resulting in the entire workout disappearing from the PM5 memory. I didn't think it was possible to delete workouts without the app and a USB or doing a reset.

Curious as to what I may have done, I opened up another workout and hit the units button and then the display button (not at the same time). Same result, that workout is no longer in my list of workouts.

It's not a major issue and I use Ergdata if I'm doing anything important, but for this one I hadn't finished looking at my data.

What exactly does the "Display" button do and does it have a function that deletes or hides workouts? Is there any way to get them back? Does it also remove the missing data from the monthly totals and lifetime meters?
