Ribbon Chart Xaxis labels problem

Good morning,
I'm trying to use the ribbon chart resource (Ignition Exchange | Inductive Automation) but I have an Xaxis issue as in picture

As you can see the time in the tooltip is correct but the Xaxis labels are showing wrong values, to be precise the labels have a 30 minutes negative offset.

What could I check to fix this problem?

Thanks for the help

If it can helps, I find the "position" property that was set to 0,5 and so there was this offset of 30 minutes.

I set to 0 and now it's shown perfectly.
