Highlight shining even disabled on the server

I’m trying to make a shopping system that when the mouse hovers over something it glows, so i did it in a more efficient way using only localscript with RunServices and Mouse.Target ( because clickDetector needs serverscripts to work ).
I notice that there is a problem when I enable the highlight ( turns true ) on the client, the client item and the server item shines, as if I enabled the highlight on both sides, however the enabled option on the server side remains off ( false ).

server test
