SOFAplotHRTF 'MagHorizontal' issue

plotting over an already existing axis without opening a new figure beforehand leads to azimuth sign error in plot 
Example:
hrir = SOFAload('path\____.sofa');
figure;
SOFAplotHRTF(hrir, 'MagHorizontal', 1); % looks fine
SOFAplotHRTF(hrir, 'MagHorizontal', 2); % sign error
