How much sugar did you add? The preservative here is sugar, and the mechanism of preservation is reducing the water activity so much that nothing else can grow. The resulting sugar jelly should be much denser than the fruit.
If you fruit sinks, the specific gravity of the jam might not be high enough.
This doesn’t look right.
Normally, the fruit should separate out on top.
