Change in the IMM008:
Previous version of the form had "Visa Office Requested: ". This question was taken off in the new form.
Change in Fee Payment form:
$550 payment now applies to Caring for Children class and Caring for People with High Medical Needs Class.
IMM008 change was made most likely on November 24th. Fee payment change was probably made in the very last week of November.
Either way, both these changes are redundant and I feel you should be fine. Worst case, you can send them the updated signed forms once you receive your AOR.
