Update: Although the 'software updater' continued to show only the blank white box, but indicated there was updates to install I went ahead and ran it through the installation process.
With the plain white box there was no way to see 'what' the updates would be. But, after selecting 'install', the Terminal Emulator opened and showed the installation progress as it normally does. When the update was complete the message, "The Software on This Computer is Up to Date" also came up as normal. So the only bug appears to be just the blank white box not revealing 'what' the updates are. (As shown in the image I submitted 8-9-2018). Hope the info is of help!
