There is an inconsistency between "Permissions Schemes" "System Scheme" + singular and plural forms, creating lack of consistency.
We invariably use:
`permissions schemes`, `permission scheme`, and `permission schemes`.
`system scheme` and `system schemes`.
To qualify as the same feature, a check needs to be performed each time one of these statements is used.
Observed: In `.channel_header.groupMessageHasGuests This group message has guests` doesn't need to specify `message`.
Expected: `This group has guests in it` should be enough (and is more coherent).
Observed: `.invitation_modal.confirm.sent-header Successful Invites`.
Expected: The above needs a rewording like `Invites successfully sent`.
