Randomly Deleted all my data in the Table

It was a great plugin until I wanted to add an extra field to my table. I clicked save to make sure it wouldn’t erase anything. Then clicked “+ Add New Field” and when it refreshed the page all of my content was gone and nowhere to be found. I even took the time to redo my table twice and the same thing happened when I went to add another new field. Thank goodness I found this bug before handing it over to my client!
