[BUG] startIndex changes after draging the end slider grip

[dimention]

Hi, I'm having trouble with slider. When the chart loads, I do zoomToDates() to last month dates, so it sets the first date as first of the month and the end date as 31st of the month, but then if I move a bit the second slider grip (end date), the first grip doesnt move, but the startIndex decreases by 1 and the date changes.

I'm using amcharts 3.21.12 with angular 4. In the images above I log the startIndex on chartReady (A) and zoomed (B) events.

Any chance of a working demo so that we can experiment on your setup, and possibly figure out the issue?
