Why is my withdrawal statistic negative?

The withdrawal statistic is made to show the withdrawals and deposits made by the token creator. If a token creator withdraws his tokens from MintMe (any amount) this statistic will increase, and it will decrease if the token creator receives deposits of his own token. So, if the sum of deposits is bigger than the sum of withdrawals, then the statistic will be negative.
Example: User B has 10 tokens from User A, who is the token creator, and decides to make a deposit of his 10 tokens to User A, as the token creator has not made any withdrawals of his token, this statistic would be -10.
