hurco vm10i changing lead in lead out by itself

Hi weve got this machine on winmax and it changes lead outs mainly by itself sometimes. It happens mostly as Ive noticed, when there is a short lead out from an contour, for example, 2mm in normal direction. Or even when there are small radii in the contour, like R0.8, after which it has to continue in a straight line for couple of mm then lead out, it will create chamfer instead of radius. It had nothing to do with cam software or postprocessor, it is because of machine parameters and software. On other machines mainly fanuc or haas, the same program will run normally. If I add short 2mm normal lead out from a contour which ends as a straight line, it will make that straight line at an angle! If i change or prolong that lead out it will make it like it should be. Ive tried looking in machine settings and parameters but no luck in finding what is causing that behavior.
