I have a trip fact defined as a ‘single select’, which can be applied to any trip and set with one of 4 values (eg. 1 – apples; 2 – pears; 3 – bananas; 4 – oranges). When saved the trip will show the correctly selected item, for example 3 – bananas. Unfortunately, the value seems to reset to the first value in the list (in the example 1 – apples) after an unrelated edit of the trip.
The trip fact values can be re-selected and save, which lasts until the next edit. It can be worked around in the short term but is a bit precarious and easy to forget.
