r - ggplot2 stat summary mean issue - mean now has an oscillating line - issue with saving data.frame?

Question

I hope this finds you safe and well. I am having an issue with my graphs. Yesterday I created waveforms (or a linegraph of means over the course of a time series). I created the graphs and saved the datasets as csvs (note these are relatively large files) - everything looked fine and great. Today, when I opened the files I saved it now has an oscillating mean (which was not their yesterday). Is it possible that the dataset saved in a strange way (note I used write.csv using the default settings)?

Any help would be greatly appreciated.

q <- ggplot(Data, aes(x=time, y=Value, color=Condition,linetype=Chromophore)) + 
  facet_wrap(~Channel, scales='free') +
  geom_vline(xintercept = 0, linetype = "dotted", color="black", alpha = .2) + #accentuate origin
  geom_hline(yintercept = 0, linetype = "dotted", color="black", alpha = .2) + #accentuate origin
  geom_line(stat = "summary", fun.y = "mean") + #show group means   
  labs(x = "Time (s)", y = "Mean Oxy-Hb (uM)") + #label axes
  theme(text=element_text(size=12)) + #set label font size
  scale_linetype_manual(values=c("dotted", "solid"))+
  theme_minimal() #set theme

plot(q)
