I have not seen this before ...can you share the file with me so I can have a look to see if I can determine what is happening?
Send it to LiveCycle8@gmail.com and include a description of what the issue is.
Unfortunately, I can't share the file with you because of the confidential data within the form. However, the problem seems to went away by itself when I add an additional item to the drop down list. Thanks for your input.
