Morphology
The image of a small insect in a food item conveys directly that a tiny defect can spoil an otherwise pleasant whole, so a learner who knows 'fly', 'in', 'the' and 'buttermilk' can infer the figurative meaning. This is a straightforward metaphorical extension (similar to 'a fly in the ointment') that is cross-linguistically accessible, making the expression compositionally transparent.
Etymology
The phrase fly in the buttermilk comes from the picture of a little fly falling into a bowl of white buttermilk and making it dirty and not good to eat. That's why it now means 'a small problem that spoils an otherwise pleasant situation'.
