Unable to disable composite model

[Anonymous]

I'm trying to publish a PBI report to a report server, but I keep getting the below error message: 

All of the data sources in the report come from SQL via DirectQuery, but when I was originally designing the report I loaded Excel data so I could test how the data needed to be organized to get the visualizations that I wanted. Once I finished the design I deleted all Excel tables so I'm only left with DirectQuery. Here is the structure of my data model:

The calendar and key measures table were created in PBI Desktop and each of the other tables are DirectQuery. I also have no M:M relationships. Based on this thread (https://community.powerbi.com/t5/Issues/Unable-to-disable-Composite-models/idc-p/482033#M30066) I should be covered, but I'm still not able to publish to a report server. Any idea what is wrong?

It looks like the issue is my Key Measures and Calendar table. I guess I didn't think of "import" as something created within PBI Desktop, but rather something imported from an outside source. I recreated the calendar table in SQL and deleted the Key Measure table and it worked perfectly.
