kaje62,
There highlights are in your listing because you indicated the same text color as the template background color, so the text can still be read.
If you revise the listing and change the text color, the highlights will be removed. You can revise active listings via the following process:
1) Locate your listing in your Saved Listings folder, make any necessary changes, and save.
2)Check the box next to your updated listing in your Saved Listings folder and click the “Get html” button.
3) Copy the html in the popup box.
4) Locate the item on eBay and click the "Revise Item" button.
5) Click "Edit Description" then click the "Enter your own html" tab.
6) Paste the copied html in place of what's there and save your changes.
I hope this helps=)
