I am trying to make list plots with the ErrorListPlot function. I have two datasets (ds1 and ds2) of which one plots nicely (ds1) and the other just give blank plots. I cannot see any difference in the way the datasets are set up so I am puzzled about why there should be any difference between them. I get no error message.

Here is my code:

Needs["ErrorBarPlots`"]
ds1 = Dataset[{
<|"Sample" -> 1, "variable" -> "variable1", "mean" -> 1.`, 
 "min" -> 0.7662`, "max" -> 1.3051`|>, <|"Sample" -> 1, 
 "variable" -> "variable2", "mean" -> 0.0202`, "min" -> 0.011`, 
 "max" -> 0.0371`|>, <|"Sample" -> 1, "variable" -> "variable3", 
 "mean" -> 0.0001`, "min" -> 0.0001`, 
 "max" -> 0.0002`|>, <|"Sample" -> 2, "variable" -> "variable1",

 "mean" -> 0.0511`, "min" -> 0.0431`, 
 "max" -> 0.0606`|>, <|"Sample" -> 2, "variable" -> "variable3", 
 "mean" -> 0.0001`, "min" -> 0.`, 
 "max" -> 0.0001`|>, <|"Sample" -> 3, "variable" -> "variable1", 
 "mean" -> 1.`, "min" -> 0.665`, 
 "max" -> 1.5038`|>, <|"Sample" -> 3, "variable" -> "variable2", 
 "mean" -> Missing["NA"], "min" -> Missing["NA"], 
 "max" -> Missing["NA"]|>, <|"Sample" -> 3, 
 "variable" -> "variable3", "mean" -> 0.2117`, "min" -> 0.1521`, 
 "max" -> 0.2947`|>}];

ds2 = Dataset[
{<|"Sample" -> 1, "variable" -> "variable1", "mean" -> 1.`, 
 "min" -> 0.8506`, "max" -> 1.1756`|>, <|"Sample" -> 1,

 "variable" -> "variable1", "mean" -> 1.`, "min" -> 0.6516`, 
 "max" -> 1.5348`|>, <|"Sample" -> 6, "variable" -> "variable2", 
 "mean" -> Missing["NA"], "min" -> Missing["NA"],

varList = DeleteDuplicates[ds1[All, "variable"]] // Normal;

ds1[GroupBy[#variable &], 
  ErrorListPlot[
    Style[{{#, #2}, ErrorBar[{-(# - #3), (#4 - #)}, 0]}] & @@@ #, 
    Frame -> True,
    PlotTheme -> "Scientific", 
    PlotStyle -> {Black, PointSize[.015]}] &,
  {"mean", "Sample", "min", "max"}] /@ varList

And this is the results:

Dataset 1: I get one plot like this for each sample, displaying points with error-bars.

Dataset2: I get one plot like this for each sample, displaying blank grids.

Does anyone have any idea on what is going on with dataset 2? Thanks!
