Why is Toolbox stuck on Datagrip 2016.2?

I was trying to figure out why there were subtle differences in Datagrip between my laptop vs my desktop.  AT first I was chalking it up to my desktop being windows and my laptop being Linux, but then I realized that there are bugs I'm seeing on my Desktop that I know I reported that were fixed in 2016.3.

Looking closer I noticed that my desktop was still on 2016.2.  I did "check for updates" and it told me I was up to date, and I went into Jetbrains Toolbox and told it to check for updates and it too told me there were no updates for it.

Going to the Datagrip website downloads 2016.3 and I've now successfully (manuall) upgraded to 2016.3.  

I know the toolbox application can find updates cause it had a message telling me Rider had an update.
