Based on your description of the concern, it seems like they may be environmental factors that affect radar in the area you are setting up the Approach R10 within.

If you continue having concerns, I recommend sending me a direct message after recording a short video clearly showing the issue occurring, and a photo showing the full environment of the setup from behind the R10 in the direction the unit is facing to record shots.
I will then provide further instructions for gathering the info from you to review further on our end.
