Filter list differs when looking at the same data using different endpoint

[jscook2345]

Compare https://qa-reports.linaro.org/api/projects/6/suites to https://qa-reports.linaro.org/api/suites/?id=144

Note that there are many more filters listed for the projects endpoint than the suites endpoint.

The filters work on the suites endpoint, but are not displayed when you click on the filters button.
