I have a maintenance plan that Reorganizes, Shrinks, and Stats for all of my databases. Why is it that it only updates Stats on certain tables and not all? Am I doing something wrong?

I am doing the following in order:

1 - Reorganize Index Task: All Tables and Views
2 - Shrink Database Task: Limit 50 MB, Free space 3%
3 - Update Stats Task: All Tables and Views

Any recommendations to do this better will be great!
