Add user in CC button disappeared

[CDG64]

In updated my LS version to 12.5.2.3 and the Add user to CC button doesn't show up, despite the changelog saying : 

• Fixed: LAN-17569 Adding users in CC when creating a help desk ticket was no longer possible after the update.

With my admin account (with a helpdesk licence) I can add a user in CC, however as a typical user (no helpdesk licence), nothing shows up.

See screenshots attached.

Thank you for your help.

This fixed ours.  

Check "Users may add other CC users" under Configuration > Helpdesk Settings > General Settings

Hello there!

Would you mind double-checking that the ticket type in question has the option "User may add CC users" enabled? You can find this setting under Configuration > Ticket Content in the Ticket Types section. The checkbox should be ticked to enable it for a ticket type.

Hey, thank you for your answer.
I've checked, it is enabled.
