Which include files do that is consistent, but reordering the includes sometimes changes which are affected, apparently randomly.

That could mean that some include file(s) have errors (or that Qt Creator thinks that they have.

Please also make sure that your .includes actually contains the directory(ies) that you need.
Please be aware that there was a behavior change that made Qt Creator stricter with resolving the includes, see e.g. https://bugreports.qt-project.org/browse/QTCREATORBUG-10359

If that doesn’t resolve your problem, please create a bug report (bugreports.qt-project.org), best with a minimal example attached that exposes your problem.
