Road sign not in Highway Code

PLEASE NOTE: I submitted the following report (number 4546525) and you closed it as a duplicate but did not state which report it is a duplicate of (and I couldn't find it), leaving me with no way of seeing any futher updates on the issue. So I am now trying again. Please can you either close it again but this time making sure to provide a link to the open report on the same issue, or alternatively please can you leave this open until fixed and provide updates on this report. Thank you.

=================================== There is a road sign for northbound vehicles that is an upside-down version of the "you have priority over oncoming vehicles" sign. In that orientation, it is not a sign in the Highway Code, and it is totally unclear whether it is supposed to mean you have priority or you do not have priority. Needs to be either turned the other way up, or replaced with the correct sign for give way to oncoming vehicles, as appropriate. ===================================
