I feel I have told you earlier also when you study Horoscope Matching you look at both the charts and not single chart. There is something known as Gun milan and also Grah Milan. Gun milan is from Birth Nakshatra while Grah milan is matching of all the planets and also the 7th house and its lord and Karka.
If the Grah milan is good , you really do not need to worry about anything else. Let me tell you one thing that No horoscope matching in this world is perfect, every horoscope will have some issues. You just need to see if there are no major issues that could be life threatening or can bring major disaster. rest everything is workable.
