Number show up in call logs when using 67

I have a AT&T cell and new Magic Jack home phone service -

I was testing it and found that if I call MY MJ using the cell phone and use *67 the caller I'd on Magic Jack shows unavailable BUT in my Magic Jack call log my Actual cell number is shown in the list with time and duration

I tested it five times and it happens every time so I asked a friend with Verizon to call using *67 with the same results

Her number showed up on my MJ caller ID as unavailable but her actual number shows up in the MJ call log 

My question is why does my actual cell number show up  in my home phone call logs if I use At&T and *67

I thought *67 was used so people could not get the callers number

I need to keep my phone numbers PRIVATE
