Sorry, but I don't consider this an answer. This isn't a matter a one corrupt template. This is 317 templates that are "corrupt" by your definition when migrated over. Yes, I am certainly aware that I can delete and recreate all 317 templates, but that is hardly a "solution". The only real solution is to go to edit each template, put a blank line under the bottom item, start typing the name of the item above it until it autocompletes, then click on that one and start typing the name of the item above that. That way I don't lose track of what items were in each of the 317 templates. When I get to the top of the list I end up with one duplicate at the top, that I delete. Now each item on that template has been recreated. Repeat 317 times. I'm sure I'll have a great day(s) at about 60 seconds per template...
