wrong auto_prepend_file

When I go to optimize firewall wordfence shows a different auto_prepend_file:

/home/zkgbh9yy9b5d/public_html/.grid_compat.php

Actual server file:

/home/zkgbh9yy9b5d/public_html/

There is no /.grid_compat-file

wordfence also shows LiteSpeed/lsapi server config

But I see no evidence of a litespeed feature on the server

Please advise
