LSM9DS1 interrupt pulse

I have configured Gyro and Accelerometer to generate interrupt on Data-Ready event on Int1 and Int2 pins. I also left at default 0 value bit LIR_XL1, which, according to the documentation, makes interrupt request NOT latched. However, when I power-on the sensor, after finishing configuration (ODR for sensors, etc.), about 1 msec later (ODR is 952 Hz) respective interrupt pins go up and stay up - that is it appears that they got latched!

My preference would be to get a pulse on the interrupt pins which will be repeated when new data sample is available - that was my understanding of what NOT Latched interrupt means.

So I misunderstand something?

Please advise!
