I created a pretty simple tile for a single value visual where I am using the 'percent from previous' as the main metric I want to show. This tile is made up of three columns, a date, measure, and the percentage from previous. The date and measure are both hidden leaving just the percentage from previous. But the value shown in my explore is not the same as the value being shown in the single value visual, my tile is returning a null value or something that is just not the same. Any advice as to why this might be would be great!
