Steve, Unfortunately this is not an issue that we have heard of but also make sure that the setting on the inside of the dispenser under the cap is not fully open as this could cause the issue to occur. There should be numbers and a small arrow that the smaller number means a less amount. It could also be a issue with the dispenser itself.
