Strange output

I'm seeing multiple entries and also the description is cut off after the first space.

Here's my setup:

```
Plug.Telemetry.ServerTiming.install([
{[:phoenix, :endpoint, :stop], :duration, description: "Endpoint Duration"},
{[:phoenix, :router_dispatch, :stop], :duration, description: "Router Duration"},
{[:phoenix, :live_view, :mount, :stop], :duration, description: "LiveView Mount Duration"},
{[:core, :repo, :query], :total_time, description: "Ecto Query Total Time"},
{[:core, :repo, :query], :decode_time, description: "Ecto Query Decode Time"},
{[:core, :repo, :query], :query_time, description: "Ecto Query Query Time"},
{[:core, :repo, :query], :queue_time, description: "Ecto Query Queue Time"},
{[:core, :repo, :query], :idle_time, description: "Ecto Query Idle Time"}
])
```
