> We do errorCount on properties present in in-memory data-structure and have isVisible attribute set to true. 
> If there are properties retrieved from server global configurations and not present on ui global metadata, We don't set it's isVisible flag explicitly to false and so they are a part of the in-memory data-structure with isVisible attribute to true.
> Such condition could arise When global configuration on the server is changed via API creating a new property whose value is invalid according to UI validations.
> OR
> Post-install removing a property from UI metadata whose isVisible attribute was false and had invalid value . This might happen during upgrades.
> As a part of solution We should set isVisible attribute of such properties to false. Global properties need to be in UI metadata with isVisible flag set to true to be displayed. We are not showing these properties anyways as they are not in the metadata and shouldn't do errorCount on it as well.
