As per subject, I think you should be able to see received upvotes even if they grant no rep change.
As you can see in this (double) screenshot, there are 3 answers with upvote after the last one recorded in recent activity
The "summary" tab only shows the "Top 5 Posts" (see the caption in your screen shot). I'm not really sure by what measure these items are ordered, but the posts you are missing don't seem to have made it into the top five.
To see all posts switch to the "reputation" tab.
