I fixed it! I'm not sure what I did previously, but somehow I had 2 marriages between the same people. One had the marriage date and one did not. I deleted the marriage with no date and now it's all cleaned up. I am curious, however, why it wouldn't show as a second marriage for the two. I was only able to find this by scrolling through the timeline of the husband and finding the second marriage entry with no date.
Thanks for reaching out to help.
