Sony FX9 MXF Files recorded in 4K Log and imported to FCPX

I would like to know why my Sony FX9 MXF Files recorded in 4K Log and imported to FCPX come to the timeline coloured instead of Log Look.

I wanted to apply a LUT and colour grading in post, but somehow, despite of having been recorded in Log, FCPX import them with colour applied.

Thanks in advance

The application has probably applied the appropriate LUT for that camera. If you want to remove the LUTs, select the clips in the Browser and set Camera LUT in Settings in the Info inspector to None.
