Hi Michel,
This should work as you expect, and I have just tested to confirm that I
see the correct behaviour under Camelot 1.6.16.
The one caveat is that the common name is optional. If it is not
present, the scientific name will be used instead.
Overall the expected process is to make this work as you expect is:
1. Ensure the name style is set to "Common"
(
https://camelot-project.readthedocs.io/en/latest/administration.html#application-settings)
2. If the settings were changed, stop and then start Camelot again to
have the change take effect.
3. Under the "Species" menu for your survey, ensure the species have the
"Common" name set.
Hope that helps,
