Hello Eva,

I created a missing value indicator for "?" and then I imported the file using the column types from your screenshot. But I'm getting different results (im running 19.3.6). For the first 3 keys you listed I didn't see the issue but I did see it on the last one. I have created a bug for this that you can follow at
https://www.labkey.org/home/Developer/issues/issues-details.view?issueId=41213

Thank you for helping me repro this!

Best,
Chet
