Rmarkdown document not rendering properly in Shiny App - r

Question

I have a parametrized rmarkdown document based on Shiny inputs.
The rmarkdown pdf renders properly when the app runs locally. However when hosted on the shiny server it produces \end{landscape} at the end of each table.
Here is a snippet of the rmarkdown code:
---
title: "Custom Analysis Report"
date: "Last compiled on `r format(Sys.time(), '%d %B, %Y')`"
output:
pdf_document:
mainfont: Times New Roman
fontsize: 11pt
header-includes:
- \usepackage{booktabs}
- \usepackage{longtable}
- \usepackage{array}
- \usepackage{multirow}
- \usepackage{wrapfig}
- \usepackage{float}
- \usepackage{colortbl}
- \usepackage{pdflscape}
- \usepackage{lscape}
- \usepackage{tabu}
- \usepackage{threeparttable}
- \usepackage{threeparttablex}
- \usepackage[normalem]{ulem}
- \usepackage{makecell}
- \usepackage{xcolor}

```{r setup, include=FALSE}
library(knitr)
library(kableExtra)
```
```{r echo = FALSE , warning = FALSE, message = FALSE, eval = TRUE , results='asis'}
if (nrow(org_profile_df1()) >= 1){
options(knitr.kable.NA = 'NA')
org_profile_df1() %>%
kable(align = "l",
format = "latex",
longtable = T,
booktabs = T,
caption = "Organizational Profile") %>%
kable_classic(full_width = F) %>%
# column_spec(1, bold = T, color = "red") %>%
kable_styling(latex_options = c("repeat_header", "bordered", "striped"),font_size = 4, position = "left",
#,"striped", "scale_down"),
repeat_header_continued = "\\textit{(Continued on Next Page...)}") %>%
#kable_paper(full_width = T) %>%
row_spec(0, bold = T) %>% landscape()
}
options(knitr.kable.NA = '-')
```
org_profile_df1() is a reactive dataset that is generated by shiny parameters. There are other such reactive datasets that get generated based on whether they exist or not (the if-statements). After every one of these tables a blank page with \end{landscape} appears (see also picture). However when I run the shiny app locally this does not appear. Only when the app is hosted on Shinyapps.io does this occur.
I have included a picture of a reactive table. There are special characters such as % and : in the reactviely generated tables.
