Polefig export to *.pol files seems to be broken

The export for Polefig in *.pol files seems to be permanently disabled (see Screenshot)

A look in the source code reveals:

ExportPolefig::ExportPolefig()
    : DialogMultisave{
        "ePol", "Pole figure export", QStringList{"dat", "lst", "csv", "pol"}, "peak",
        gSession->peaksSettings.size() > 0}
{
    setFormatEnabled("pol", gSession->params.interpolParams.isStandardInterpolation());
    setFormatToolTip("pol", "Intensities only, with reference to interpolated standard grid");
}

The export for this format is enabled/disabled by the gSession->params.interpolParams.isStandardInterpolation() method

bool InterpolParams::isStandardInterpolation() const
{
    if (!enabled.val())
        return false;
    for (double step : {1.0, 2.0, 5.0})
        if (stepAlpha.val() == step && stepBeta.val() == step)
            return true;
    return false;
}

enabled.val() == true is one of the conditions necessary for isStandardInterpolation() to also return true. And here is where I see a potential bug in Steca since this enabled is initialized with false and its value is never changed again.

Therefore an easy fix would be:

ExportPolefig::ExportPolefig()
    : DialogMultisave{
        "ePol", "Pole figure export", QStringList{"dat", "lst", "csv", "pol"}, "peak",
        gSession->peaksSettings.size() > 0}
{
    gSession->params.interpolParams.enabled.setVal(true); // solves problem
    setFormatEnabled("pol", gSession->params.interpolParams.isStandardInterpolation());
    setFormatToolTip("pol", "Intensities only, with reference to interpolated standard grid");
}

But I'm not sure what the intention was.
