Chromium-based browser limitation: there is no concept of "user style", which would override the page's style. uBO uses a few tricks which works partially in the current case (try and see difference with ABP).

For the current case, a better cosmetic filter can be used to alleviate the lack of user style, try:

bucksfreepress.co.uk###__nq__hh:style(visibility: collapse)

Since the warning is to only demand a visitor to turn off their blocker, I will add a filter to uBO's filters to remove it.
