[ROOT] No end bars on error bars despite SetEndErrorSize(10)

Hello!

When executing a macro an excerpt from which is shown below, I get no
horizontal end bars on the error bars, although I have used
SetEndErrorSize(10) in rootlogon.C (and verified it in the macro via
gStyle->GetEndErrorSize()). The values are drawn properly, error bars
are shown, too.

// Code snippet:

TH1D *histos[2][12][6];

// **************************************************
// [ reading the histograms with errors from a file ]
// **************************************************

for(unsigned obs_cnt=Ann; obs_cnt<=Ask; obs_cnt++) {
    linestyle=1;
    asymm_corr_nocorr_graph->cd(panel++);
    
    asymm_corr_nocorr_legend[obs_cnt]=new TLegend(0.57, 0.8, 1, 1);

    asymm_corr_nocorr_legend[obs_cnt]->AddEntry(histos[goodpico][input_bc][obs_cnt], 
						"A", "PL");

    histos[goodpico][input_bc][obs_cnt]->SetLineStyle(linestyle++);
    histos[goodpico][input_bc][obs_cnt]->SetMarkerStyle(24);
    histos[goodpico][input_bc][obs_cnt]->Draw();

    histos[wrongpico][input_bc][obs_cnt]->SetLineStyle(linestyle++);
    asymm_corr_nocorr_legend[obs_cnt]->AddEntry(histos[wrongpico][input_bc][obs_cnt], 
						  "B", "PL");
    histos[wrongpico][input_bc][obs_cnt]->SetMarkerStyle(25);
    histos[wrongpico][input_bc][obs_cnt]->Draw("SAME");

    histos[goodpico][input_nbc][obs_cnt]->SetLineStyle(linestyle++);
    asymm_corr_nocorr_legend[obs_cnt]->AddEntry(histos[goodpico][input_nbc][obs_cnt], 
						"C", "PL");
    histos[goodpico][input_nbc][obs_cnt]->SetMarkerStyle(28);
    histos[goodpico][input_nbc][obs_cnt]->Draw("SAME");

    asymm_corr_nocorr_legend[obs_cnt]->Draw();
  }
  asymm_corr_nocorr_graph->Update();
}

Thank you for suggestions,
