Problem with dynamic vdb column metadata - for salesforce source w/import property

There seems to be a problem with the column metadata for dynamic vdb with salesforce source. Here is my scenario.

1) Deploy dynamic vdb w/SF source (attached sample). The VDB sets the 'importer.ModelAuditFields' property to 'true'.
2) expose the vdb as a jdbc source, then connect to it.
3) get the column metadata for a table using
connection.getMetaData().getColumns(null, null, fullTableName, null)

When the vdb has 'importer.ModelAuditFields' = true, some of the columns are missing. Here is a comparison for one of the SF tables

AccountFeed, (importer.modelAuditFields=false)
--------------
Id, ParentId, Type, IsDeleted, CommentCount, LikeCount

AccountFeed, (importer.modelAuditFields=true)
--------------
Id, ParentId, Type, CreatedById, CreatedDate, IsDeleted

with modelAuditFields=true, the audit fields (CreatedById, CreatedDate) are added, but CommentCount and LikeCount are missing. It seems to clip to the same number of cols as the modelAuditFields=false case.

Second issue (minor)
-----------------
The display name for the property is slightly wrong.
line 75 of SalesForceExecutionFactory is 'Audit Model Fields' - it should be 'Model Audit Fields'.
line 362 of SalesForceMetadataProcessor - same thing. also suggest changing the description to something like 'Determines if the salesforce audit fields are modeled'
