Trouble importing CSV address file

[BBonbike]

Version 3.7.0 installed and mostly working great except for importing my own CSV address book file. I even exported the Personal address book (with 2 entries) to test1.csv using commas separate values, and test2.csv using tabs separate values. So far I have not been able to re-import either of these 2 files no matter what combination I try. Even though Sylpheed 3.7.0 created these 2 file I keep getting this error, "Error reading CSV fields".
This is very puzzling because importing my OE6 inbox.dbx worked flawlessly. BTW this is all on my Win10 Pro 64 22H2 ThinkPad laptop.
Any help would be greatly appreciated, thanks.
