Third person Character "kicks" objects away

I use the character from the Animation Starter Pack as the player’s character (i will replace it later) for testing of my project. The problem i encounter is when the character touches other objects they do not move normally but instead the are thrown like they are kicked by the character… When the objects (chairs and closet) interact with other objects the collisions an physics work fine. I tried to increase the weight of the objects but the result is the same… What is wrong with this character? may i need to ask this on the Animation section?
Thanks in advance!
