If you confident with CSS selectors, then consider using Modification (click on the </> icon on the top).
Let me know if that helps.
Alternatively, try the following:
1. Select the element the way it's posisble
2. Click "Expand Selection"
3. Click "Edit" > "Text/HTML". Check the HTML.
If the HTML still does not contain the desired layer, repeat (1) and (2) and Expand Selection one more time. Keep expanding unless you find the element you would like to amend.
