How to remove highlight in PDF in DTTG?

When you highlight text in DTTG, one of the options you are presented with is to highlight/underscore/overstrike the selected text. You can undo this action on the annotation toolbar. However, when you finish editing, undo is no longer possible. How can I remove the highlight from the PDF?

Such as having a previously highlighted text which I no longer want? The eraser from the annotation tab does not work on highlights.

Touch the highlighted text and select the trash can from the popup menu.
