As I describe in the title, when changing the folder name from "work" to "research" to ensure consistency between the folder name and the related website section, the sidebars that appear on the right side of each project page do not display.
The folder contains the Markdown files for each of the projects, in which the content to appear on their respective pages is defined, including that of the sidebars.
I've tried several solutions but haven't been able to fix it, so for now, I've reverted to the previous folder name. From what I've been able to investigate, the issue involves the respective Markdown files of each project and the index.html file.
