I’m surprised to see that the separator character in the lines you report is a tab rather than a comma. Did you save the results file on your device and then open it with a spreadsheet editor, by any chance?
I edited your message to properly format the lines you report, and now you can see that they contain no line-break—you probably saw “second lines” just because of how the lines were rendered onto your screen, but they are not real second lines
If you saved your results file with tab separators, you need to pass "\t" instead of "," as the sep argument of read.csv:
all_results <- read.csv("results.csv", header=F, sep="\t", quote='"', comment.char='#')
