XY Chart adjusting cell width cellEndLocation?

I have an annoying problem with the XY Chart, where my column series doesn't start and stop at the correct timestamps.

I have posted a picture of my chart, inside the tooltip is reads the Start (23:00) and End (23:15), which is the data that i have inside each of my datasource. The problem is that the column starts at the correct location, but the end value overshoots into the center of the grid cell. That why i have the cellEndLocation in my header.

Does anyone know how i can fix this.

I have posted the Json for the series setup, one with the complete JSON (Series Raw) and one where i have removed Line, StepLine and CandleStick, called (Series only with Column)
