They did make an economy short share. Along with that, the moldboard was longer, narrower, and had more roll to it. If I remember right, it was designed to plow sod, and turn it over well to cover. Back in a time, when farming was more diversified. Fields would be sown for grass for hay, then 4, or so years later, after alfalfa, or clover reached it's peak, it was then turned over to pasture. Somewhere within the crop rotation, sod was plowed under,and a commodity crop was planted starting the cycle allover again.
If you can't adjust the plow's drawbar far enough over to align the wing tip of the share, with the inside of the left rear tire, then it is going to kick sideways, doing what it is doing now.
You may be able to replace the share, and get what you need. But, you may need to replace the moldboard, and possibly the landside also. That being said, oem parts are nearly non-existant, but there is hope. There is a fellow here in Ohio that makes new "Blacksmith" shares. Last year (I think) I guided a fellow in Washinton State to him, who had an IH Fast Hitch Plow Chief plow, and had exhausted all efforts to find new parts, and was afraid he'd have to find another tractor to plow his acreage he grow produce commercially. I sent him the link to Ploworx, and within a week, he was back to plowing. The fix wasn't cheap, but a lot cheaper than replacing his tractor and all.

Otherwise, it may be an idea to look for another plow. Up to you.
