Line chart combination numeric x-Axis and discrete markers

[Deaniebean]

I am trying to create a line chart that has an numeric axis scales, I want to apply conditional styling to the marker points, I know that this is done with the property markers.discrete but I'm having trouble applying it:

here is an example sandbox: https://codesandbox.io/p/sandbox/apexcharts-responsiveness-px56nz#

Basically I'm trying to set a standard size of 6 for all markers and for one of the lines it should only display the markers at the Integer values:

markers: { size: 6, discrete: [ { seriesIndex: 0, dataPointIndex: [2, 3, 5, 6, 8, 9, 10], size: 6, },

Still all markers are being displayed? How would I do this correctly?

Any help is really appreciated. :)
