@Esile-1448, Thanks for posting in Q&A.
For this issue, there isn't a way to have work contacts showing in the personal profile contacts. It means that Intune couldn't manage setting or data in Personal Profile and this is by design.
However, you can refer the link below to export contacts in work profile and import them in personal profile.
Also, you can contact MBUX software support to see if there will be better idea.
Hope it can help.
