Acrobat Pro installed on new computer, no longer able to use comment markup tools for polygon

I own Acrobat professional, version 11.0.  I recently purchased a new laptop with windows 10.  I deactivated my account on the old laptop and downloaded and install Acrobat professional on the new laptop.  When using pdf files, I typically need to use the Comment tools to markup the documents.  Today I noticed that the Drawing Markups that I use won't allow me to use the "draw cloud", "draw ploygon" and "draw connected lines" options.  I use the draw polygon option very frequently.  These 3 options are the only ones that are Grayed out and not available to use.  All the other tools appear to be available.  Why all of a sudden are these 3 not available?  S
