I'm mostly developing liberal viewpoints on a lot of social issues, but I still find that I frequently empathize with conservatives rather than liberals during debates or discussions. Conservative talking points still resonate in my mind, even if my liberal-influenced intellect finds them unsatisfying.
You are doing it wrong.
I think of myself as moderately conservative, though I test as liberal on some of those test sites.
In any case, the proper way to do it (IMO) is to judge each issue on its own merits. It's okay if you agree with the conservatives on some issues and with the liberals on other issues, and perhaps occasionally with neither. What's more important is to think it through, and to be willing to change if the evidence requires that.
And some issues are difficult to decide. It's okay to sit on the fence with such an issue.
