Gitlab Jira smart commits not updating time and comment field

Hi all,
I linked GitLab (Saas) and Jira using tokens and urls; when I commit and push to the repo commenting with #comment and #time keyword for smart commits, comment field and time field are not updated in jira tracker.
I am wondering why or if pusghing towards GitLab I should rely on a different strucure of the smart commit. I use sourcetree as tool but I saw that also pushing from command line the issue persists.
Any hint on this?
