GeoListPlot and PlotStyle discrepancies between Version 11 and 12?

With version 11 this program work well. In data we have longitude, latitude and a number that indicate a class. And this program draw a map with stations.

GeoListPlot[data[[All, All, 1]] , 
 PlotLegends -> data[[All, 1, -1, 1]], 
 PlotMarkers -> {Style["\[FilledCircle]", FontSize -> 20, Black], 
   Style["\[FilledDiamond]", FontSize -> 20, Red], 
   Style["\[FilledSquare]", FontSize -> 20, Blue], 
   Style["\[FilledUpTriangle]", FontSize -> 20, Yellow]}]

But this program don't work with Mathematica 12. Why ? Only the map appear, but not the stations.

I think it must be a bug. Anything other than Automatic for the Plotmarkers seems to fail. I would log a call. Also the examples at https://mathematica.stackexchange.com/questions/123952/plotmarkers-in-geolistplot-do-not-work do not work anymore.

My data :

{{{GeoPosition[{36.867, 30.733}], {1}}, {GeoPosition[{36.274, 
     23.017}], {1}}, {GeoPosition[{36.667, -4.483}], {1}}, \
{GeoPosition[{38.176, 13.091}], {1}}, {GeoPosition[{36.405, 
     28.086}], {1}}}, {{GeoPosition[{41.283, 
     2.067}], {2}}, {GeoPosition[{44.413,

Perhaps you should now wrap GeoPosition around your coordinates? Could you give a short sample of your data?
