My MBP has no click bar; normally, you click the trackpad, preferably toward the front, although there is a prefs setting for "tap to click" which I have unchecked currently to try to simplify the situation.
Agree, it's hard to advise about skipped updates without specifics, and I will try to work up a list.
1. I forgot about those new-fangled trackpads, but that doesn't preclude possible failure from being a reasonable guess.
2. If you "Ignored" those updates you can get them back by clicking on "Reset Ignored Updates" under Software Update in your menu bar.
