Average difficulty rating - show wrong or multiple sessions
A yellow/light blue highlight in the time distribution charts highlights your time, where relevant.
Rating scores out of 10.0 show the average difficulty rating chosen by users, where 1.0 is "Easy" and 10.0 is "Hard".
If a puzzle is opened more than once, including by loading from a saved position, then this is potentially a significant aid so it is listed as being completed with 'multiple sessions' for the purpose of the best time/average rating displays above.
Minor aid is defined as no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or using highlighting aids (show repeated digits, show broken inequalities and show valid/invalid placements [slitherlink] only). Major aid is any and all other use of the solving aids except for 'show wrong'.

Are you maybe pressing F5 by accident? I intercept this where possible, but perhaps on your machine it is reloading the page - if you're on a laptop or similar the F5 key could be right next to a number key so easy to hit by error.
The only way the numbers can vanish is if the page reloads (or you press 'reset' and confirm you want to, which obviously you aren't doing!). You could try saving regularly, since on a reload it would then just go back to your most recent save.
You can however view other players' statistics and their comments in the tables above.
