Cannot select the hiring manager in the offer team when creating job offers

We are using position hierarchy, but have noticed an issue when creating job offers. Under the offer team section, recruiters cannot select the hiring manager. It seems to default to one individual and is read only. However, in situations where there are multiple managers for a certain position this is causing issues as we cannot distribute the new joiners across the managers. It will always default to the same manager and cannot be edited.

However, in other flows e.g. the edit pending worker flow, when there are multiple managers in the position, you have the ability to select from the list of managers in that position.
