I'm in a new job that adheres to CMMI standards so they're picky about everything. There is a header in my document that contains three images grouped together. (One picture and two word-art things.) In the process of working on the content of the doc I somehow deformed the header so it "doesn't look right". (It's stretched horizontally, or vertically, or the letters in the wordart parts are spaced out too much or slanted - depending on how I fiddle with it.) I've tried a few things to fix it and I'm getting frustrated. Here's what I tried:

Fiddling with the size/shape of the images directly - got close but apparently close isn't acceptable. It has to be identical to the way it is in the template.

Took an older document with the correct headers and managed to strip out the content, but when I try to copy the content of my bad-header doc into the good-header doc, the bad header gets copied along with the text. Do I need to do one page at a time? (I guess I'll do that while waiting for help here, but my god will that be time consuming!)

For the future, is there any way to either lock the header to prevent it from changing shape, or an easier way to fix it if it does get deformed? A coworker says that the issue has something to do with compatibility mode. The good-header document says it's in compatibility mode and the bad-header doc isn't.
