In SonarQube v6.2 , various test-related metrics were integrated into a single “Coverage” metric, as noted in the v6.2 Upgrade Notes
SonarQube 6.2 now has only one type of coverage (MMF-345 - Simplify code coverage support in SonarQube) which merges unit, integration and overall coverage that were badly managed depending on which language(s) and kind of projects you are using. If you had defined quality gate conditions on integration or overall coverage metrics, those quality gates will be automatically updated to use the “default” coverage metric. In this case, you should review those quality gates to make sure that they still represent your requirements.
As a side note, if you were using the Web API to query the overall or integration coverage metrics, you should update your scripts.
The idea really is to have SonarQube as a consolidator of all the possible coverage data you may wish to import (in a flexible/scalable way). That evolution also allows tracking 0 coverage on files that have executable code without associated coverage data. And ultimately it lets each underlying tool reports their specific suite/results in the most suitable manner (and you should consult those reports if you want a more fine-grained view into coverage results).
There’s no specific workaround to recommend to differentiate the two in SonarQube.
This is probably what you read already, so if so, sorry
