By default player last names are not shown on our Sportfix platform, instead their first names are shown along with the first letter of their last name so that the privacy of each player is protected and for participants to still be able to identify different players who have the same first name.
This setting can be changed in the system settings. Navigate to: Settings -> System and then click on the Sportfix Tab.
If you would like to protect the identity of individual players you can create an alias for them as described in this help article. Alternatively you can hide all player details from being published online.
