I agree need more info, but as other stated should help. my nephew who switches from longbow to recurve had same problem, and then he asked me. After watching him shoot, I explain the problem which others already stated. though the form is good and anchor the same, and the bow weight is the same on both bows, the recurve is center cut and the longbow not, so we went to shop and found some different spined arrows and bam he was good. But as stated working the arrow plate will help as well Mr. Bear did this alot I believe. One other thing, when doing a swing draw with the recurve you have to draw the string straight back. Typically, the recurve does not have the lateral stability the longbow does, and if you don't draw straight back, will get some limb twist, which in turn will cause erratic arrow flight and much frustration (been there), I only found this problem after watching Mr. Asbell video on how he shots and had a friend watch me and that was the problem, stopped torquing he limb and was shooting skoal cans. Hope this help. Don't get frustrated, just keep your form the same and look at your tackle and say "what is the differance that would cause this", keep your string waxed.
