Hi @Anonymous ,

You may enter into Query Editor in Power BI Desktop, go to APPLIED STEPS, find the step named "Changed type" , delete this step.

Or you may go to File -> Options and settings -> Options ->CURRENT FILE ->Data Load, don't tick the option "Detect column types and headers for unstructured sources", restart the Power BI Desktop to take effect of this change.

Best Regards,

@v-xicai @VijayP can those two tickable options be set to unticked by default please? It would appear that whenever a dashboard is published and then downloaded as PBIX from the service, those options re-tick themselves, causing problems with refreshes with previously functional dashboards. Having these ticked by default is REALLY annoying.
