Weird Pattern of Dots in Images Shot with new OM-1

I just purchased a new OM-1 Mark II camera (late August 2026). I recently noticed what looked like dust on my sensor in some of my images - there were dark circles in the same location in many photos with a light background and not much detail. Today I took a test photo to verify my strobes were working so I was not focused on anything at all. When I reviewed my photos I noticed the "dust" looked like small circles in a pattern. At first I thought the circles might somehow be on the subject I was shooting, but when I reviewed my photos I shot on my next dive I saw this same pattern of circles in some of my images that had a light, blurry background.

I took a number of photos above the water when I was evaluating the camera but I never saw these circles, even after thoroughly re-reviewing the image.

I have been shooting with a 90mm lens in the AOI housing, with the FLP-08 port. I am also shooting with the 60mm lens and so far I haven't seen these circles in a pattern with the 60, but I have seen the dark spots in like dust on the sensor.

Has anyone else experienced this problem?
