If you encounter a dashboard that has recently started to experience issues, such as blank sections after loading, unresponsive date range parameters, or issues with parameters in your dashboard, a Tableau bug may be the cause.

A Tableau bug that causes a small percentage of content to have some parameters randomly swapped out with others was discovered during content deployments to Data IQ®. This bug may also cause parameters to be duplicated. In this case, a dashboard may be referencing one parameter in one field, while referencing the duplicate in another.

We are working with Tableau to determine why this is happening and how to prevent it from happening in the future. Communications will be sent out once we have more information from Tableau on a solution to this issue. Until then, the workarounds below may help to resolve issues with your parameters.
