Not in any way connected with Ardeca, but this may explain the various discrepancies noted:
Maybe the local (or regional) distributor has requested the changes, and to save on graphics cost has just used the same templates. Although of courese if I were Ardeca I may advise against the practice as this may lead to confusion, as was happening here.
