Adobe PDF annocations being flipped when flattened

[biba.doa]

I've added some text box annotations to a PDF and used Preflight to 'flatten annotations and form fields' however, it's flipping the annotations horizontally so the text reads upside down and at the top of the document not the bottom where I added it. This used to work fine. Any ideas please?

Does it also happen if you do it by running this code (from the JS Console, for example):

this.flattenPages();

?

That works perfectly!! You are a total life-saver! I've wasted so much time trying to solve this and you come along and whip up the answer out of nowhere!! Thank you SOOOO much!!
