Camera alighnment non-capture image Falcon pro2

I’ve been having issues doing the camera alignment on Falcon2 Pro using latest version of lightburn. I got through everything up to the capture image after burning the 4 corner and 1 center target. All works well until I do the capture image part. The space where the captured image should show up stays black but my camera still functions in the other image area. Is there some adjustment that I need to make someplace? Very frustrating. Thanks in advance for any help.
