The servo pwm output always has a value even if you haven't personally set it to anything.

It can be the 127 that pwms are set to by default in the User_Initialization routine, or if uninitialized altogether then it will be some random value.
When you don't explicitly give it a value it will retain whatever random value happens to already be in it's allocated memory location. Most often this random value is zero.
