Hi Omar,
I believe this is a global configuration. Once this has been removed by the administrator user, no other users that login to IM will be able to see the "Info" field when selecting the Licenses tab. Please let me know if you have any further questions on this.
I would suggest testing if your users accounts are able to re-add the field. If so then this may be a question for our Global Service Center team, to have the license names changed.
Kind regards,
Ryan
