I've recorded 2 recordings in 1 meeting. But when I click to convert, there was only 1 recording!

The first recording is around 30 mins long. The second recording is 8 seconds. When I checked the meeting's folder, there was 2 files: "double_click_to_convert_01.zoom" (465,5MB), and "double_click_to_convert_02.zoom" (2,9MB). Although the sizes of those files are different, they converted into 1 video (the 8-second video). I cannot find the 30-min video. Can anyone plz help?
