Thank you @martin.R and @joels. It turns out that there is a known issue with bind_rows where it sometimes strips data frame attributes like variable labels. Here, I mean "variable labels" as in the Stata sense, a description of the variable in addition to the variable name. In Stata, they allow for a convenient way to make, for example, table and graph legends. I am still adjusting to R when it comes to specific features that I relied on in Stata.
The package [sjlabelled](https://cran.r-project.org/web/packages/sjlabelled/index.html) has a command for getting variable and factor labels, so I am probably just going to save those and then reapply then once I am all done with bind_rows.
Thank you both for the suggestions.
