Handicaps / stroke index

Hi  ok 2 things - firstly , just wondering why my s62 is telling me that my handicap mark is dropping to 24.2 when i entered 28 5 rounds ago, and my average strokes per round is 100, a classic 28 handicap !

Also, how do i see the stroke indexes ? I can see the dots on the watch and in the app indicating which holes i have 1 or 2 shots on, but i would like to see the stroke indexes on each hole ?
