First record is header checkbox missing

[Bryan_Edwards]

When I go to add a base, then import a spreadsheet, the “First record is header” checkbox is missing. Not sure if I am doing something wrong.

I have tried it in Safari 12.0.1, Brave 0.25.2 and Chrome 70.0.3538.102

I have searched the community but didn’t find any answers.

Thanks.
