The current code in \src\Mod\CAM\Path\Main\Gui\Job.py (line 719) ignores selected stock selections. In case of e.g. cloned stock objects it defaults to the first item in the combolist, showing a wrong stock selection.
The cause lies in comparing different strings to find a label match, but one string object is generic (short name) while the other one has a suffix created during the clone process. The strings never match and the ridgid string comparison fails. I recommend using a partial (needle in haystack) string comparison.
