Time Slicer linked to data but displaying as blank visual

[ronanfenelon]

I have a slicer linked to simple date listing. other slicers set up the same way with the same format of data are working and two are not working correctly. Any ideas on how to fix this?

Hi @ronanfenelon, 

Please check if the Maintenance column/measure does have data when [Health and Safety] is during Oct 2019 - Dec 2019, and [Planting and Filling] in is in Nov 2019 - Jan 2020.

If possible, please share the pbix file of the report with us. 

Best Regards,
