Editing a HubSpot meeting removes Contact associations

I seem to have a bug within HubSpot where, after a Meeting Event is created and associated with both a Contact and Deal, if I return to edit a property, the title for example, the Contact associations are removed.

I noticed this when querying the Meeting list via GraphQL and receiving a correct result. When I updated the Meeting title, the associated Contact is removed. This is shown on both the GraphQL response as well as within the HubSpot interface
