Wall coverings interrupted at corners

[Anonymous]

Hi - I have sucessful applied wall coverings to my building but one corner is not displaying properly on model view. It is perfect in plan view but there is a gap running up the building... I cant figure out how to fix this. (See image below)

Have you tried opening the dbx for the covering & setting the cavity to zero
then in plan view un-mitre the corner using the red hot spot.
If I have got this incorrect please post the plan view.
