hi girls!
it is semi fixed lol
turns out the tracks are out of level..how we fix that, i dont know!
anyway because its not straight the snip lock we put on it was catching and thats why it was sticking, we've moved the lock down a bit so it doesnt catch anymore, and we sprayed some silicon spray along the tracks to lubricate it a bit, its made a huge difference!
i went to close the door after it was done and closed it with as much force as i was used to and slammed it big time! hehehe thanks for the replies girls
