2 Zoom Invite links on same outlook invite

For some reason when I send out an Invite from outlook and add the zoom link by pressing on the zoom bottom in outlook the link is created correctly on the location field and body which is great. But days later after people have been added/removed from the invite suddenly the room location link is different to the link in the body of the invite. The only thing I can think of is if a colleague goes into the back end of my zoom to add an alternative host would that effect the link?
