Replace 'Loaded' with 'Installed'
In acf-apk-tools every package action can be either: Install, Upgrade, Delete
So after installation (and/or upgrade) it should be listed under “Installed”-tab (not “Loaded”). The page header should say “Installed Packages” (not “Loaded Packages”)
Tested with: acf-apk-tools 0.4.1-r0
