I have prepared a dataset, and connect it to a table.
Although the dataset is correct, some entries are displayed twice and some, although deleted from the dataset, are still displayed. I have delete and reconnected the data already…in preview is fine but not when I publish it.
Have a look through Wix Support for Datasets: https://support.wix.com/en/wix-data/database-collections
Read about ‘Accessing Your Sandbox and Live Data’ and ‘Syncing Data Between Sandbox and Live Database Collections’ and ‘Deleting Fields from a Database Collection’ and others to see if any of the guides help you.
