Delete Multiple Messa in os 10.2.1 not working as it should. A bug or i dont know how to use it?

In blackberry os10 when i'm in the hub and I go to "settings>Display and Actions>Delete On: Handheld Only (that's the option I choosed)" It works fine when i delete message one by one (it deletes from my device, but it keeps it on my account so i can keep reading this in other devices) but when i choose to select multiple message and then delete them that when it goes wrong and deletes de emails from the blackberry, the server and in conclusion to the rest of my devices. Anyone knows if i'm doing something wrong or if this is a bug from os10?
Thanks a lot!

It is a bug. No fix for this time being.

Keep in mind, when you delete prior or multiple messages, mire times than not you are deleting more than just email. So delete on won't work. I agree it should be able to work if only email from the same account selected.
