NUnit - tests not running where categories contain hyphens

We're currently on TeamCity 10.0.5 and any attempt to run NUnit tests with categories that contain hyphens is finding no tests to run. If I attempt to run the same tests locally through command line it works. The command that works locally:

nunit3-console.exe ...tests.dll --where cat==TCM-1234

On TC, I am installing the nunit3 console package (3.9.0) as part of solution build and I have tried both NUnit 3.0 and command line runners without success. The build log shows the following:

[18:53:05][Step 2/2] Test Filters
[18:53:05][Step 2/2] Where: cat==TCM-1234
.

Any help is appreciated.
