Problem with the 2 for 1 Entry card and guide 2021

I subscribed to the magazine following the Money Saving Expert recommendation for the 2 for 1 thing, in particular for access to the Eden Project.  Well, the Eden Project does not figure in the list of participants and MSE admit they got it wrong.  Never-mind there are plenty of other sites to visit so I looked at the ones in the catalogue for Wales - 20 of them - except only 19 are listed in the description.  I was interested in number 18 which is placed on the map somewhere near Tenby in Pembrokeshire.  I looked up the exact address in the guide and blow me down the address is at Menai Bridge Anglesey!  What the heck.  Further checks reveal at least 8 other numbered sites are definitely in a completely wrong location.  I am very confused; at least Cardigan Castle looks right, but I am uncertain about the other locations.   I have no idea if similar problems are to be found for other regions in the guide, maybe other subscribers could advise.  Perhaps a corrected guide could be issued? I don't really want  to work my way through the whole booklet to correct the numbering system.
