Flying on Saturday I kept getting my Freda check timer popping up at irregular, but less than 10 minute intervals.  I suspected duplication and looking in the "timers" option today I can see 4 occurrences of the Freda timer (I've only ever set up one).  I don't know what caused this, but it's easy enough to correct by deleting the extra 3.

That's weird. Can you reproduce this by logging out and back in again, perhaps it happened then?

When I started using SD I defined a persistent timer 'Tank umschalten' (meaning 'switch fuel tank' in English). At one point I decided to introduce English as my main language on board, so I deleted the German timer 'Tank umschalten' and created a new one 'switch fuel tank'.

If I use SD now, showing only the English language timer, and then log out and in again, the German language timer reappears, additionally to the English language timer. If I log out and in again another time, SD shows

Switch fuel tank
Tank umschalten
Tank umschalten

The German language timer is added once more each time I log out and in again.

While doing these tests I noticed all surface features are activated automatically when I log out and in again. Is this a bug or a feature?
