**What you are seeing**

I filled in 'Markdown description' in the macro config, was warned about unsaved changes, saved, and the description was gone.

---

## Why it happens

The save path never passes the description through, even though the underlying store accepts one. The unsaved-changes guard still counts a description edit as a change, so you are prompted to save something that is then dropped.

---

## What to do

Do not rely on the macro's description field. Set a description on the document from the Capable Markdown library page instead.
