Casting to your left, my first post

Right handed.  Learned to cast either hand (in my early 60's), but stick with right when accuracy is a must.  Usually use an overhand cast for ultimate accuracy.  I'm not too bad with a left hand roll cast.  Almost always cast with both hands on the rod...whether long or short cast.  I don't use a backhand cast all that often, so not the best cast for me.

Can't offer advice on how to correct your problem.  I can say casting right handed to the right doesn't make for the best accuracy for me either unless I use an overhead cast.
