Although this bug may have been reported before, it is best that you report it as well to Zendesk, using the “Submit a Request” on the top menu bar: Support. Bug tracking is not done in the forums even though the devs may sometimes view the forums. More bug reports will result in the bug being prioritized and may result in the bugs being fixed faster.
