Results not showing up in results section

Hi @kyuk 
The info regarding your issue is present on the support page. I have also mentioned the same below, please check if it resolves your query.
------------------------------------------------------------------------------------------------------------------------

Your data source for the specified visualization is not compatible with the visualization in its current state. Several possibilities could be happening here:

• The question was originally a different question type. Click on the visualization. If this doesn't resolve the issue, re-select the data source (e.g., the question linked to the visualization).
• A breakout was applied that the visualization did not accept. Change the visualization to a different type, and then change it back to the original visualization type.
• An incomplete results filter can cause this. Removing or finishing the filter can solve the issue. See Filtering Results for more details.

Thanks but none of these options solved the problem for me.
