This site labels this specific theme with a single initial, L — worth reading closely, since unlike the first two, this theme is explicitly a reservation, not a positive report.
This site describes it directly: a frequent reservation is that only two ingredients are named, and some buyers want a full panel before ordering more — worth crediting this site for including a critical theme alongside the two positive ones.
Worth reading the inclusion of this specific reservation as a meaningful signal against one-sided, uniformly positive feedback summaries — this site names the same transparency gap it addresses elsewhere on the page.
