DataGen Formatting Error

I attempted to generate random email addresses by using the DataGen Number type with the following parameters set:

Start: 1
End: 500
Pattern: test#@test.com
Randomize instead of step - checked

Expected Output:
test365@test.com

Actual Output:
test365.@testcom

For some reason the period is removed from .com and shifted to before the @ symbol. I've found a way to work around this by simply generating a name and number and using property expansion to prepend the value before an email extension but thought this was still a bug worth reporting.

Please review and advise. Thanks!
