Infernal "could not be fully matched to feature files" message

Warning: The given test results could not be fully matched to the feature files. Please make sure that the correct locations were defined.

I have a couple of test suites running in an ADO YAML pipeline that run fine. The problem is that the doc's don't generate properly for them. It will work with one test suite if I comment out the references to the other but not when I have them both referenced. Both test suites are located under the same directory so I assume the feature files are being being found. The TestExecution_#.json files are identified in the logs so I know they are in use. The task looks like this:

    - task: SpecFlowPlus@0
      displayName: 'Generate the SpecFlow + LivingDocs reports'
      inputs:
        generatorSource: FeatureFolder
        projectFilePath: dotcom and web App
        projectName: Web App Testing 
        testExecutionJson: |
            dotcom and web App\**\TestExecution_2.json
            dotcom and web App\**\TestExecution_1.json
        projectLanguage: 'en'
        output: 'LivingDoc\FeatureData.json'

I have tried way too many permutations to get this to work and it's still not working. Hoping someone can spot the error..

Thanks
