iPad Air 5th gen mirrors to two screens on projector

Hello! I am trying to connect my ipadAir 5th gen to a 1080p projector (Marantz vp-15s1) using a usb-c to hdmi connector. My ipad connects to the projector no issue but two screens that mirror the ipad show up. How do i just make it mirror one screen? See picture below for reference.

would appreciate any tips or assistance. Ive tried using stage manager - mirror and extend setting s. It still ended up the same.
