First I'm sorry for any mistake English is not my first language, I believe in the phone version of the site (I haven't gotten to see it on the computer yet) that some tags seem not to be updating ex: female protagonist, maybe it's a problem in the version of the site on the phone but I could be wrong.
this is something thats been happening for a little while. one mod/dev said to search the tags manually using the tag: in search function. ex. tag:female_protagonist
