Many stickers are set up to add the profile to a category, and that seems appropriate in this situation. It is not required for a sticker to do this. If the sticker adds and category and the category was also added manually, the category will appear only once on the profile page.
The format used for sticker documentation is intended to be clearly understandable by all, but I think that it can be challenging for many people who do not write computer code to understand it. Basically, whatever text you enter after post= will appear in the sticker after the string "International Order of Odd Fellows,"
PS - There was some additional [extra] verbiage in the sticker text that I removed a couple of minutes ago.
