National Highways Authority Of India [NHAI] — Money deduction at mansar toll plaza

Today i went to jalandhar from pathankot.Two toll plaza comes in the way of the route.First is mansar, second is chollang.At mansar toll plaza i paid 105 for the toll rate and at chollang i paid rs 90. In the evening when i was returning from jalandhar to pathankot, At chollang i paid 45 which is correct but at the mansar toll plaza again 105 was deducted from my fasttag which is not correct, As money should be deducted less than 105 as i was crossing the same toll plaza within 24 hours. Can you guys plz expalin me that is anything wrong at toll plaza mansar machines, if yes plz check it.
Thank you
