Problem with horizontal lines in geom_bar

[VitorBSP]

Hello Everybody! I'm developing an R markdown document with geom_bar graphs, but I have a little problem, with horizontal lines, like blocks, in my graphs design.

I have a df like this:	Grupo	Valor
Documentação	275
Documentação	56
Documentação	275
Documentação	56
Documentação	350

And my code is:

bar_g2<-function(data, y, x,category, manual_fill){
  data %>% 
  ggplot() + 
  geom_bar(aes(y={{y}}, x = {{x}}, fill = {{category}}), stat='identity') + scale_fill_manual(values={{manual_fill}})
}
bar_g2(Des_Grupo, Valor, Grupo, Grupo, gt)

So, the graphs is like this

But I want the graphs is like this: (without horizontal lines)

I noticed I have one graph without this horizontal lines

But for this graphs I used group_by, so I tested for the other plor and it works too

Have a more simple way?
