You'd have to show us a screenshot of the schedule and the schedule scheme. It is possible that some of your scheduled parameters are using Calculation Units and others are using your Dimension Preferences. If those are all showing metric (or Imperial) - not a mix - then it is possible that the objects themselves are computing some of their values themselves and ignoring the global unit settings...
Cheers,
