Crab Apple Tree

I’ve planted this crab apple tree last autumn. It was in a pot and I’ve planted it at the same level. Now it’s doing this:

Should I have buried the graft? Should I dig it out and replant deeper? Or should I add some more soil to the area?

I had adventitious roots like those develop from the rootstock on one of my apple trees a few years ago.  I left it and did nothing.  The tree is fine.

Thanks, @BobTheGardener. I’ll just leave it then.
