Synchronizing: children folders can't be checked/unchecked

Hi,

Just updated from v8 to v10 and found some details missing.
When using synchro tool, in comparison results sometimes parent folders are checked in grey. This means that some of it contents are updated and some not.
But, that grey check cannot be changed; you can only check/uncheck contents one by one. This must be an error.

In v8 that grey check could be cleared (meaning every childen won't be updated) or solid-checked (meaning every children will be updated).

In v10 you're doomed to check children one by one which can be extremely tedious and break the whole idea of Synchronizing.

Is there any reason for this behaviour?

Regards.

I think I've reproduced this, and I've opened a bug report for it.

Thank you!
I hope to see it fixed soon.

Regards.
