Getting check() warnings with dataset documentation

[Hong]

I have a package with a couple of included datasets, and I'm getting a persistent warning on running check():

R> check()
...
-- R CMD check results -------------------------------------------------- SAR 1.0.3 ---- 
Duration: 2m 18.5s

> checking for code/documentation mismatches ... WARNING
  Variables with usage in documentation object 'ms_catalog' but not in code:
    'ms_catalog'

  Variables with usage in documentation object 'ms_usage' but not in code:
    'ms_usage'

The datasets in question are a couple of .Rdata files, and the documentation is just this:

#' Sample usage dataset
#'
#' Dataset of anonymised transaction records from the Microsoft online store.
#' @format A data frame with 118383 rows and 3 columns.
#' \describe{
#'  \item{user}{The user ID.}
#'  \item{item}{The item ID, corresponding to the items in the [ms_catalog] dataset.}
#'  \item{time}{The date and time of the transaction, in POSIXct format.}
#' }
#' @source Microsoft.
#' @seealso
#' [ms_catalog]
"ms_usage"


#' Sample catalog dataset
#'
#' Dataset of item descriptions from the Microsoft online store.
#' @format A data frame with 101 rows and 3 columns.
#' \describe{
#'  \item{item}{The item ID, corresponding to the items in the [ms_usage] dataset.}
#'  \item{name}{A short description of the item.}
#'  \item{category}{The item category.}
#' }
#' @source Microsoft.
#' @seealso
#' [ms_usage]
"ms_catalog"

As far as I can tell, this is the recommended way of documenting datasets with Roxygen, and the generated Rd files also conform to what's specified in "Writing R Extensions". What am I doing wrong?

I'm running R 4.0.2, on Windows 10. This problem didn't occur when I was using R 3.x.
