CC Adobe Acrobat DC update

​I have Adobe Reader installed, however, any idea why my CC Apps manager constantly prompts me to update Acrobat DC even though I am only on the photographic plan? 

The moment I update (download) it, I am informed that my trial period has expired, and the update option changes to 'Buy Now'.  The other apps that I'm not subscribed to do not behave in this way.

It's annoying because it prevents me from selecting the 'update all' option.

**  I have now read in the CC forum that this has been a known issue for about 3 years, but Adobe seems unwilling to address it.
