Cannot access updated Add-Ons

I am new to Kodi 17.1 and finding the learning curve rather steep so would really appreciate some advice.

I can navigate to My Add-ons and find numerous items which I can update and receive a notification that they have updated. However, the RUN button at the left side at the bottom is greyed out and not accessible and I am unable to start any of the listed programs.

How do I access these programs?Huh
