Anyone did furusato-nozei through e-tax?

Hello,

This is my first year doing Furusato nozei and I have already got the donation gifts from Rakuten.

I chose the option to do everything online through e-Tax (I think I will need to download a csv file for this), so I guess there is no way to switch back to having each municipality sending me the donation certificate or using the One-stop service.

My concern is that I have a middle name, and even though when filling out deliver address and “注文者情報” I have put my name exactly like on residence card (spaces and order), I noticed when checking back on the order information on Rakuten, there was no space between my middle name and first name in the “注文者情報”. Since e-Tax will be reading the csv file retrieved from Rakuten, will it be a problem if my name is not in full-width or missing spaces?

I have problems signing up for things before with my Rakuten credit card before because of this space, and it was settled with just a call, but for Furusato Nozei, will it be more tricky or straight out impossible to prove?

Thanks in advance!

Side note: I did freak out a bit and reviewed my address, however, the space was still there. Just when I go to the order screen, the space mysteriously disappear.
