dropdown lost field name

when using dropdown fields it’s mandatory to use the “Tag” option to set a list of available values. it causes fields without name on email notifications and a weird visualization of profile on front-end and back-end

example of the problem (dropdown fields without name in frontend):

is there any way to solve this?

thanks in advance
