R plotting code behaves differently for CSVs containing different data formatted the same way

Question

I have two CSVs for experimental data measuring the effects of a two values of a single variable. Basically the code is the same except for the name of the data frame reference is changed and the chart title. However, when I plot for one of the values two of the lines are not plotted.

CSVs:

R Code

For oneac:

library(ggplot2)
ggplot(oneacFFAAVSE, aes(x=Hours, y1=Lv1neg.Mean, y2=HSA1.Mean, y3=WBC11.Mean, y4=Osg15.Mean, group = 1)) + 
    geom_errorbar(aes(ymin=Lv1neg.Mean-Lv1neg.SE, ymax=Lv1neg.Mean+Lv1neg.SE), colour="#000099", width=.1) +
    geom_errorbar(aes(ymin=Osg15.Mean-Osg15.SE, ymax=Osg15.Mean+Osg15.SE), colour="#FFA500", width=.1) +
    geom_line(data = oneacFFAAVSE, aes(Hours, Lv1neg.Mean), colour="#000099") +
    geom_line(data = oneacFFAAVSE, aes(Hours, HSA1.Mean), colour="#990050") +
    geom_line(data = oneacFFAAVSE, aes(Hours, WBC11.Mean), colour="#009900") +
    geom_line(data = oneacFFAAVSE, aes(Hours, Osg15.Mean), colour="#FFA500") +
    labs(title = "Nitrogen Depleted Media with 1g L-1 acetate" ,
         x = "Time (Hours)" ,
         y = "FFA (µM)")

For fiveac

library(ggplot2)
ggplot(fiveacFFAAVSE, aes(x=Hours, y1=Lv1neg.Mean, y2=HSA1.Mean, y3=WBC11.Mean, y4=Osg15.Mean, group = 1)) + 
    geom_errorbar(aes(ymin=Lv1neg.Mean-Lv1neg.SE, ymax=Lv1neg.Mean+Lv1neg.SE), colour="#000099", width=.1) +
    geom_errorbar(aes(ymin=Osg15.Mean-Osg15.SE, ymax=Osg15.Mean+Osg15.SE), colour="#FFA500", width=.1) +
    geom_line(data = fiveacFFAAVSE, aes(Hours, Lv1neg.Mean), colour="#000099") +
    geom_line(data = fiveacFFAAVSE, aes(Hours, HSA1.Mean), colour="#990050") +
    geom_line(data = fiveacFFAAVSE, aes(Hours, WBC11.Mean), colour="#009900") +
    geom_line(data = fiveacFFAAVSE, aes(Hours, Osg15.Mean), colour="#FFA500") +
    labs(title = "Nitrogen Depleted Media with 5g L-1 acetate" ,
         x = "Time (Hours)" ,
         y = "FFA (µM)")

Please don't judge the data it's a new assay and I'm ironing out the creases. More duplicates are on the way too!

Thanks
