csv section import allows erroneous csv; creates sections that cannot be accessed (404) or deleted

Hi Lyla,

The CSV importers in general are considered "mostly deprecated," and if they are buggy, we'll probably just remove them.

Is there some reason you were using CSV and not the .xls importer? Just that it was easier to find the link to the CSV?

Thank you for the fast response! Yes the xls looks like a better way to go.
As to why that wasn't my initial choice:
I'm trying to teach a not super tech savvy co-worker how to set up everything needed for a school year and do it in the most straight forward way possible. The import csv link for sections was the only way available, besides entering them by hand, when I was looking at the main section page.
I have used the xls import feature before, though in my mind (incorrectly) I assumed I should only be editing that sheet when initially setting up things for the school and that now that we're in our second year, it'd be risky to play around with such a comprehensive document. Also, when you click to import by csv, it gives you clear instructions/example of how to do it, whereas the xls import is something that I've mostly been editing by looking at what is automatically generated and copying it. At least to me, the existence of instructions and import csv link both implied that that csv import was the "proper" way to do it.
In retrospect, I think the csv import might have worked a little better in my situation as well because I could see my co-worker being overwhelmed by this giant excel sheet.
Finally, what would you recommend as the best way to remove the faulty sections? There's no way to go to their detail pages and doesn't seem to be anything other than options to add on the main screen. Is there any way to get rid of them short of changing things manually in the database? Thank you!

Also, not sure this is related, but now whenever I click on a user to go to their info page (or my own user page), I'm getting a server error. The only things I've changed intentionally are adding the messed up sections and using the import xls function to put some dummy data in for two new demographic fields (one a selection field, on a integer field)
