Problem with density plot due to non-finite values (stat_density)

I have been plotting density plots for various variables in a dataset of harvested animals. After finally having succeeded in plotting density plots of one numeric variable I moved to the next variable, and then got the warning message: "Removed 684 rows containing non-finite values (stat_density)". I first tried to remove all NA's but that didn't help. Any ideas?

My script:

ggplot(df, aes(x = MEATW,y=..count..,fill=factor(gr))) +
  geom_density(alpha=0.6,size=0.4) +
  scale_x_continuous(limit=c(0,30),expand=c(0,0)) +
  scale_fill_manual(values = c("#d4faad","#868686FF", "#EFC000FF","#BEafad")) +
  theme_bw()

And a sample of the data frame:

dput(df)
structure(list(MEATW = c(1243, 1500, 813, 900, 800, 800, 500, 
900, 500, 600, 400, 700, 600, 600, 500, 500, 500, 500, 600, 800,

That warning often occurs when you have set limits on an axis, which is also the case here. Running without that line: 

ggplot(df, aes(x = MEATW,y=..count..,fill=factor(gr))) +
geom_density(alpha=0.6,size=0.4) +
scale_fill_manual(values = c("#d4faad","#868686FF", "#EFC000FF","#BEafad")) +
theme_bw()

output

The code still returns that warning, but only for the three NA's that are in the data sample that you provided.

Hope this helps.
