I think maybe you've misunderstood my problem. I also see both label and field names in the designer, but the field names are incorrect. They are supposed to be the actual field names from the associated table, but instead are a repeat of the label name. I believe in your screen shot it shows the problem, because the field name appears to have a space in it, which is not allowed.
Here's some screen shots of mine:
Here's the same field as yours showing the space in the field name.
Here's the same field after changing the label.
And here's the summary showing both the same label and the correct field name that it represents. Note that the field name does not have a space in it.
I hope this helps to identify and resolve this issue.
