I am using a data source generator, that outputs a CSV for a race, as the drivers complete each lap, problem is we run many many races throughout the day and say race 1 has 20 cars, I get 20 rows on the CSV, but when we switch to a race with say 15 cars next, only 15 rows show up on the CSV, as a result, my graphic has positions 16-20 from the last race. Short of manually going in and editing the title each time (the downtime provided between these events is nil, so going in to modify that many titles would not be possible) Is there any way I can tell vMix that if it doesn't have a value, to leave it blank?

I noticed that when the row "dissappears" in this example, vmix goes to "auto" for the column select, and that auto isn't working as I want it to.
