Some of the league systems rely on manual results entry and it's not always a set of scores that SquashLevels can interpret. This sort of thing is not uncommon: 9-5, 9-6, 9-4 for instance. It could be argued that this sort of result could be pulled apart but, for now, we check for pairs of numbers that are within reasonable limits. This example will fail this check so can't be used.
If you can correct the score entry on your league system then it will be re-sent to SquashLevels and all will be well.
