Why is the target variable included in the LIME plot?

Question

I tried to prepare LIME plot to interpret my model but I have an error here. When I generate plot there is one bar for target variable and I don't know why. Can somebody help me please? I want only predictors in graph no target variable (Deaths.Caused in picture).

#inpu$targetVar is user choice target variable
#inpu$predVar are user choice predictors
#train_datas_subset is subdataset of train datas
#test_datas_subset is subdataset of test datas

form <- paste(isolate(input$targetVar), '~', paste(isolate(input$predVar), collapse = '+'))
model <- eval(parse(text = sprintf("train(%s, data = train_datas_subset, method = 'C5.0')", form)))

explainer <- lime(train_datas_subset, model)
explanation <- explain(test_datas_subset[1, ], explainer, n_labels = 1, n_features = length(input$predVar)+1)

output$limePlot <- renderPlot({
          plot_features(explanation)
})
