Red leaf patio peach trees with green shoots at the bottom

I have successfully repotted 3 red leaf patio peach trees which I got in the middle of July instead of the end of May. I thank thone gardeners who advised to do it now and not to wait for autumn.
Now my concerns are that 2 of the trees got green leaves shoots growing from the bottom of the trees. I am in doubts now if to keep them growing or remove them.
I'll try to attach a picture.
Any recommendations? Thank you in advance.

 

Simply remove them. They are grafted....see the union.....so anything below this mark is the rootstock, not what you want Black Orchid. Rest easy

 

Your advice is much appreciated. Thank you very much.
