When advancing a bar with a shortcut key, two bars are advanced with a single keystroke.

This seems to be happening on 1m, 5m, 15m, 30m, 1H, 4H and 1D timeframes.

The same is true when reverting.

However, when the bars are moved by mouse operation, they seem to move one by one as intended.

Could you please check? Thank you in advance.

Thank you very much.
