Apexcharts series out of sync

[GGSSDD]

Hi everyone.

I'm new to ApexCharts so be patient with me.
I'm trying to build an area chart that displays the value of 3 temperature sensors in a serie but i must be doing something wrong cause it's behaving erratic. I want their values to be shared in the tooltip, but with my current config when one of the 3 entities updates, the other two seem to fall out of sync and don't fill the chart from the beginning anymore, like the one that just updated, causing the tooltip not to share their values anymore.
Funny thing... when i go into editing mode it seems to display and behave as it should.
