Getting Error Message When Duplicating Fields

Question

I am using Acrobat X Pro, ver 10.1.4 to edit an existing Acrobat (non LiveCycle) form. My computer is running Windows XP, Service Pack 3.
There are three fields on my form that I want to select and duplicate multiple times (11 times down and 4 times across). The fields are one check box field and two text fields. I've used this method in the past, and nevr had any problems:
1. Click "Tools" > "Forms" > Edit
2. Select the fields by lassoing them with the cursor
3. Right click and choose "Place multiple fields"
When I do the above steps, I get this error message: "Cannot create multiple copies of this selection.One or more fields in the selection have duplicates in this form."
However, if I multiple select the three fields using the fields panel on the right side of the screen and then right click and choose "Place multiple fields", I do not get the error message and forms are duplicated as expected.
I played around with this a bit and found that when the first method fails,  if I remove one specific text field from the group of three fields, the "Place multiple fields" functionality works on the remaining two fields. If I add a third, completely new and unique text field to the group of three fields, I get the error message again.
What am I doing wrong where one method works and the other one does not?

What error message?
Are you sure that the network is really public?
