Changing button name in snipeit

I’m using Snipe-IT on an Ubuntu server, and I want to change the terminology shown in the dashboard:

Change Checkout → Transfer

Change Checkin → Return

I tried editing the language file located at:
/var/www/html/snipe-it/resources/lang/en-US/general.php
Specifically, I updated the var array like this:
‘checkout’ => ‘Transfer :item_type’,
‘checkin’ => ‘Return :item_type’,

However, the changes are not reflected in the dashboard UI. I’ve also cleared browser cache and restarted the nginx service, but the old labels still show up.

I’m using nginx, not Apache, and everything else in the app is working fine.

Questions:
Is there a specific cache I need to clear in Laravel or Snipe-IT to apply these translation changes?

Are there any other files or keys I should update to make this change across the entire dashboard?

Is it possible to automate this change throughout the app?

Environment:
Snipe-IT version:v8.0.4 build 17196 (gc29bdbdac)

OS: Ubuntu

Web server: nginx

Thanks in advance for any help!
