Breakpoint not set even then it stops here

Question

I am using Win 10 64 Bit PC with 2012 CVI program to test a function ( as below). The program always stops at this function (MeasurePressureValues) even there is no breakpoint set!

Function:

int iRet = 0;
char szDeviceId[200] = "Iso45671A";
double Double1a[4095], Double1b[4095] = {0};
int int1a, int1b= 0;

iRet = MeasurePressureValues(szDeviceId, &int1a, Double1a, &int1b, Double1b, szError);

At first call the function MeasurePressureValues() execute and once-again its act as breakpoint to execute same function.

Does anyone face this kind of issue.. what could be the reason
