I am placing a banner inside a Zone and the zone 'bubble' on the map is not centered over the correct cell but is centered over the 'Parent zone'. Additionally you are unable to place a banner in any other cell that the Zone covers. In the image below the banner is placed in X18 where i am standing. And I'm unable to place a banner in w17, x17, y17, w18, w19, x19, y19, y18,

The zone flags of this 'parent zone are:
{
