pfSense

I observed the same thing about a week ago. Performing an update from the console resolved the issue.

not replicable. Those two pages use the same function to obtain their data, so no apparent means for one to show an update that the other doesn't. Though I recall hearing same from someone else at some point, IIRC just refreshing the page a couple times made it show. Go to Diag>Command and in the PHP Execute box, put in:

[...]

and hit Execute, what does that return?

array(3) {
  'pkg_name' =>
  string(7) "pfSense" 
  'version' =>
  string(7) "2.3.1_5" 
  'installed_version' =>
  string(5) "2.3.1" 
}

which is correct, guessing it's no longer showing as described? As that output would give you 2.3.1_5 as an update available.
