My floor plan for my home has two missing sectors, one of which is for relationships, I seem to be lacking at this which makes me believe I need to correct this somehow.  The question is, How.  Any help would be appreciated.

I read that in the relatioinship part of your home, you are suppose to put things in pairs, pair of's . . .  couple in a picture, or
two animal figures, etc....   wish I could help more.  Keep Reading Books on feng shui, each one can give more and more insights.

If you have a missing sector you can correct this by placing a big mirror on the missing corneres wall on both sides and this will make the cure

Mirror is good idea.  Just be sure that you are not reflecting the wrong thing.  Just be careful.  Mirror is not really good indoor.  Just place a pair of dove or swan in your home.

Newatthis,

I believe you would have got your house facing / sitting directions right. With this you need to superimpose the 24 Mountain pie chart over your floor plans.
You then fill in the Flying Stars chart and also the house 8 Mansion chart. From here, you need to see what is in the missing sectors.

If they have the bad stars there, don't worry, you don't need to do anything. Good stars in missing sectors means you are not able to ultilize them.
You can use the remaining sectors with good stars. The best is where you have the good Flying Stars and the good 8 Mansion energy in that sector.

Make full use of this good sector together with your personal favourable direction.
8 Mansion & Xuan Kong Flying Stars work in harmony

Best regards to you,
