R10 not pick data, 9of 10 failed

If you are using the R10 indoors, make sure you are using the recommended spacing suggestions, along with eliminating any environmental factors that interfere with the radar capture. 

For reference on the spacing and setup suggestions, check the Garmin article here: Tips for Indoor or Outdoor Approach R10 Placement

To view the radar and troubleshooting FAQ, please reference the support page here: Troubleshooting Radar Features of the Approach R10

Typically the issue you are experiencing is due to the spacing of the indoor setup, or there is an environmental factor affecting the radar capture that needs to be moved away from the capture area, to allow the R10 to sufficiently capture each shot.
