I'd contact Dave - nice guy and I'm sure he'll get you sorted.
The deformation may well have been a large heavy package resting on top of your waveguides. 😱 Insured?
If you gently heat the WG with a hairdryer to soften the plastic you should be able to reset it by placing it face down on a flat surface and letting it cool. edit: is the front of the WG painted to achieve the satin finish? Paint may not like heat.
It really needs an extra mounting screw along the top and bottom edges, especially since it has the weight of the tweeter hanging off the back of it.

Thanks both. Yeah Dave was very helpful when I bought these, sorting out the best international shipping rates and so on. IIRC they were modestly priced and his graphs suggest they work well too so this thread isn't intended to imply criticism. I was perhaps naive in my implementation of them, had I not fixed them just at the corners and had I not stuck them in such close proximity to a 10" driver on the same baffle probably all would have been well. Dave also gave me the option of having them cut oval rather than rectangular, the cone part is a lot more rigid so again I perhaps made a poor choice of leaving the extra rectangular area on the front. I'm sure he would still try to help, even though I'm not exactly local, but for me this is all part of the DIY/learning experience and thinking about how to solve it has been useful in understanding what forces are at work.
I hadn't considered trying to correct the curves TMM,so thats a good thought. I think the satin finish is the plastic itself so that could be done. The issues I'm having would likely still be there - its still a thin flat area and so (as you say) it really needs supporting better than I have done. My baffle cut out didn't leave enough material to get extra screws where they would be needed though, so thats partly why I'm intending to support with a rear frame, and partly because it offers other ways of supporting the tweeter.
