Reproduction:
1. select the Radio tool
2. set its "Values" setting to something (and remember the setting)
3. select the Advanced Duplicator tool
4. right-click the Radio
5. left-click somewhere empty
6. compare the "Values" setting to the previous setting from 2.

Expected result:
the settings should match

Bug result:
the settings don't always match
(try a different "Values" setting if the first attempt doesn't reproduce the bug)
