STM32F030C6 trying to use LSE

Hi, I have a STM32F0C6 board and I'm trying to use RTC function with LSE.
It seems RTC is working correctly and I can check the waveform of LSE Clock from MCO pin.
But when I check the waveform of OSC32_IN and OSC32_Out pins by using an OscilloScope,
OSC32_IN: about 300mV flat line
OSC32_Out: about 1.3V waveform nearly LSE clock(32.768KHz).

Is this correct work of OSC32_IN and OSC32_Out?

 

please give me an information.
and let me apologize for my poor English.
thank you.
