I've created some parent ion Skyline documents using either metabolites or peptides, but when I share them with collaborators only the peptide-based ones open. The metabolite-based documents fail to open with the following errors:

System.Reflection.TargetInvocationException: There is an error in XML document (217, 8). ---> System.InvalidOperationException: There is an error in XML document (217, 8). ---> System.InvalidOperationException: Failed parsing adduct description "[M+HH]M+2O[31]"

System.Reflection.TargetInvocationException: There is an error in XML document (364, 10). ---> System.InvalidOperationException: There is an error in XML document (364, 10). ---> pwiz.Skyline.Util.AssumptionException: error reading mz values - declared mz value 592.167741 does not match calculated value 592.671653727269

I've recreated the metabolite documents as (heavily modified) peptide based ones and they work fine. Wondering if this is a common issue or a niche case, as my collaborator is running skyline on Mac in a emulator?

Thanks Rob
