warning: Skipping identical href : Possible to synchronize anyway?

[ekx27]

Hello,

I am synchronizing an calendar using vdirsyncer locally for backup purpose, but there is one issue :
There are events with the same name but different content (recurring events), is there any way to syncrhonize it anyway?
