This is a common situation in SPICE. It is the reason why people often use a 0V voltage source for current measurements. I have also created a current probe symbol specifically for the 0V voltage source. However, by default, Qspice will display a negative value for current when probing a voltage source. To obtain a positive current reading, you need to hold the shift key while probing. You can refer to this post for more information on this topic.
