Reproduced this eg with Source Medium report see https://github.com/matomo-org/plugin-MarketingCampaignsReporting/pull/83
Also reproduced this with the "Search Engines" report.
To reproduce select the visualisation
it will show data. Then select the Pivot feature using the cog icon
Then it will show now data.
Pivot feature works with the regular simple table visualisation.
Maybe a simple solution could be to simply disable pivot feature when all columns table is used. Or maybe we can get it to work.
