Anyone in a similar position? Good low and high notes, but not chest voice

I started taking singing classes about 3 months ago. I'm seeing good progress. My singing coach is very surprised to know that I can do low voice, let's say, Michael Buble - It's begining to look a lot like Christmas, Human - Rag'n'Bone, etc. And I also can do Golden - from Demon Hunters lol But I can't do mid voice/chest voice. She said this is the first time she sees this, usually people would have low and mid or high and mid. Anyone else like this?
I'm now focusing on training my chest voice, trying to find it.
