Incorrect mass under Mass propoties with intersection of structure member

Hi:

 

I am using Solidworks 2015.

 

I have a part design with 3 structure member joints together like a triangle. I have use intersection feature to "cut" the 2 intersection portions of one structure member. After that I found that the mass under mass properties is incorrect. I have try many different methods but keep using intersection feature, the mass is still incorrect. I wish to keep intersection feature because it gives me easy modification on different configuration.

 

Notes:

3 square hollow section(structure member). 1 of them was intersected by the other 2.

Mass is about 37kg before intersection but after intersection the mass became about 81kg

 

Is the problem related to intersection? or Weldment structure member? Any way to get the correct mass?
