I am on ios 7.0.4, with MCPE 0.8.1, and have experienced this. My other crops are sustainable (wheat, potatoes, carrots, melons, pumpkins), but I get less than one seed per plant on average with beetroot when tending my small beetroot garden (16 initially, now 12 plants and shrinking). I have been using bonemeal to rapidly grow these plants, to save up seeds (which has backfired🙂 )
