Content security header not updated on one of my static site pages


I have updated a Content Security Policy request header that seems to be intermittently updated and then not - which is causing some pages to display content and others not, it’s causing me a bit of a headache because I cannot figure out what to do to resolve this.

I’ve tried to clear cache and manually deploy and that fixed a couple of the other pages but this one page seems to be a persistently not updating, but then also when refreshing pages that are working they then seem to revert to the older CSP. I know it’s not my own cache as I’m testing this in Browserstack and a number of other devices - even curl -v

Does anyone have any advice or can help please?

Many thanks
