If you have a “table beta” visualization in Tranpose mode and have multiple dimensions, it will fail to transpose, instead displaying the error message “Transpose requires exactly one dimension.”. So far, so good. But there’s a problem: trying to turn off Transpose fails: the option is greyed out.
There is a workaround: hide all but one dimension from the visualization, untranspose, and display them again. But this still is a bug.
