Mods Not Removing From Server?

After installing mods to my server (police uniforms and some cars) I can’t seem to add anymore… so I removed some and tried adding different outfits and my previously downloaded mods are still being shown in my server and not my new ones.

For some reason they’re staying and I’m not sure how to fix this.

I’ve tried close everything and restarting, even renaming my server. Advice?

Delete the .rpf and .sfl from Server/cache/http-files/.
Use the search function next time.
