In the new version of Tuleap 7.1, I notice on trackers when i want to add a comment from an artifact or want to modify a list field (combo box), it's not possible to validate the changes through a button as there is no button displayed.

When I try to create a new artifact, at the end of the page, I have the validation button but but this button is not present if I want modify my artefact or add a comment.

It is just possible to validate the changes done on a one line text field, in pressing enter key after the modification.

it's a real problem for us because we are currently unable to use trackers at the moment. Can anyone suggest a fix or help in any way?

Thanks for your help.
