RAM SS - Error - Wall with no property

Question

Hi Everyone, 
 I got this error in my model. It is showing that there is a wall with no length and no property. The wall can't be deleted since it is not under 'concrete' or 'other'. 
 The ram model was created from a revit model with the ISM Revit plugin, which I think where the error is from. Is there a way for me to delete this wall? 
 
 Thanks, 
 Gerald Evan

Use Layout - Wall - Change Material - Fence, then try delete fence.

There is definitely some corruption of the data in that model. If I delete the wall with the method above it will either crash or further corrupt the data on that level type. Your best bet is to recreate this level type (copy a similar one), use the new type in the story data, and then delete the original corrupt level type altogether.
