Hi Guys,
Well well… I’ve been seeking a little bit, as it seemed really odd to me.
I reproduced your setup and indeed had the same problem.
@damies13, the added line didn’t help, not much as my own idea that led to not be able to run the test from the .robot file 
don’t know what was I thinking…
Tried to run from the suite, modified Test Cases arguments to Default, UserData has in their examples.
None worked, and I finally remembered the example .csv files they gave, so here’s a working one :
No need to play spot the difference, the twist is .csv file is separated with semicolon “;” instead of comma as in your file.
Default behavior seems to be to use the semicolon, but hopefully you don’t have to search-replace tons of .csv, and just add the dialect modifier and delimiter in the library call :
Library DataDriver file=parameters.csv dialect=UserDefined delimiter=,
More infos in this part :
Regards.
