VS 2019 dacpac file will NOT let me choose to suppress reference warnings. Any suggestions how to fix?

Question

I added a database reference to a visual studio 2019 database project. It was built by another developer, but that shouldn't matter. I point to the dacpac file and select "Same Database" as my database location and check the box to suppress reference warnings and click OK.

The resulting properties that show on that dacpac say that suppress reference warnings = false and I can no longer build my project because of reference errors.

It did not keep my selection for the suppress reference warnings setting and it will NOT let me change it back to true in the properties. I've tried to remove the reference and add it back again, the same result.

Is there something that can fix this? Some setting or something that is causing this behavior?
