Warping issues

I have an ender3pro, (magnetic, heated bed). I put the glass from a picture frame on it and the print is so smooth its reflective and smooth as glass on the bottom (besides where there was supports). One side raised off the bed just a little about 1/16". What can I do to fix?

(You can see the lines in the picture but you can't feel them at all, they feel like glass)
