Question MissingFIeldException: Field at index does not exist

Hi, I have exported the string table in csv format, and then edited some translations. When I try importing that csv file, uUnity gives me this error: MissingFieldException: Field at index '2' does not exist. You can ignore missing fields by setting MissingFieldFound to null".
Why does this happen and/or how can I set "MissingFieldFound" to null?
Thanks!

 

I renamed the key field name, but I have tried with the original name again and it shows the same error. This is the full error:
