Problem Statement/Rationale

The specified type is invalid when importing data into the collection from csv file.
No matter what type I change to, the data type of all fields is still string.
Another problem is that I cannot select a certain Field check box.

I guess this is because the first line of the csv is in Chinese, because there is no such problem after changing them to English.

Steps to Reproduce

You can refer to my screenshot and cvs file in the attachment to reproduce this problem

note: The csv file is in utf-8 encoding format
