Failed to load alert configuration?

Has anyone had this error before? I was able to set up the alert on the card. Now it's saying this when I was going to edit it. I have a summary number. I have changed chart types. (I thought domo called them cards btw?) But still not working. I deleted an alert with a similar problem. Created a new card. Set up this alert. It worked. It ran. Now I can't edit it.
