Extra and unrelated faces appear to the model after mirroring!

I made half of this model and then at the final step mirror it. The problem is when I save this model as a stp fromat and open in CATIA the model has extra faces which I don't know where they come from. Surprisingly when I save half of the model with same condition the problem is gone. what are these surfaces(highlighted in yellow in picture)? and how to get rid of them?

Hi, Milad Payvasteh
In your model there are some faulty faces which you not trim and that faces extends when you mirror half of your model.
I removed that faulty faces and all works fine
I attached some screenshots and .STEP file.

Hope, you like it.
Feel free to contact.
