Unable to change model relationships in Datamarts

[pcc18]

I'm trying to recreate a powerbi dataset into datamarts but I'm getting these error messages when deleting or updating a relationship in Datamarts. Curious to what's causing the error here since relationship changes should work the same as the pbi dataset.

Hi @pcc18 

Datamarts are in preview and as far as I am aware currently it is not possible to edit the relationships. I am sure at some point this will change.
