Hi,
It's highly probable that it's a problem of dimension conversion because you don't use the same dimension units everywhere or the main unit (the first one in the configuration) is not the same.
I would recommend you to try with that version of the plugin:

We worked on it lately to improve the conversion system in order to avoid such problems.
