Editing invite link

I DO NOT have access to branding yet somehow I was able to edit the meeting invitation link about a month ago.  I would like to remove the info that was previously added in the meeting link and I cannot do it.  Is there a way to gain one time access to remove the information that was added in?  I am so confused and frustrated that I cannot undo the changes that I have already made.  Have access settings recently changed? Is there a glitch in my account settings that initially enabled me to do this? I have zoom linked to acuity scheduling and I do not want meeting links going out to clients with the information that was previously entered into the meeting link! Who can I communicate with to get this resolved!?
