My best guess is that neither md on Linux nor the IMSM driver on Windows have an unambiguous way to determine which disk is correct, which is why it hasn't just sync'd them. So you kinda have to pick one (?) and force a sync - again I'll have to defer to someone else to answer that question but it's probably not ideal to just leave it in a dirty state.
