Adding Text since Recent Update

Since the latest update of Acrobat about 3 weeks ago I can no longer create a text box which overlays over text already in the PDF, as in hides the text underneath. I used to be able to click add text and had create a red border on my text boxes. I could place them over top of the text I wanted to hide. How do I do this in the new version? I can edit text or add text but it does not create the same well defined box or overlay. The text underneath is shown. Text boxes shown in photo below from prior Acrobat version, unable to replicate in new version.
