Right mouse click on keyboard indicator

SUMMARY

I am using 3 keyboard layouts: English, Russian and Ukrainian. And the thing is when switching policy is set as Application very often I am experiencing very annoying anomaly: switching order start to work as if it would be only two layouts - it starts to switch only between first and second layout: English - Russian and again English again after Russian although should be Ukrainian. Also when it happens if to right mouse click on layouts indicator very strange picture I see: please look in attachment. It is definitely a bug because if I have 3 layouts they should switch in usual order: 1st -> 2nd -> 3rd -> 1st... and so on. But it becomes 1st -> 2nd -> 1st - 2nd and never switches to 3rd layout. This reproduced not all the time but very often and it is very annoying. I'm not sure exactly but it seems it happens only when Switching Policy is set to Application.
