If your Choice limits have been exceeded this is most likely to be due to settings in the Activity:
e.g. If your settings under Common module settings are
- Group mode: Visible
- Grouping : None
- Available for group members only : Checked
Then a user from a group can continue to vote for the full choice. Only if they then selected ‘All participants’ would they see a ‘full’ notice and a disabled select button
The correct settings should be
- Group mode: None or Separate if using a grouping
- Grouping : None or Grouping name
- Available for group members only : Unchecked or Checked if using a grouping
so that everyone will see the full notice and not be able to select it if spaces are full.
