The vignette title specified in \VignetteIndexEntry{} is different from the title in the YAML metadata. The former is "a02_applying_cohort_restrictions", and the latter is "Applying cohort restrictions". If that is intentional, you may set options(rmarkdown.html_vignette.check_title = FALSE) to suppress this check.
