When importing an excel file using Teiid Connection, the extension properties are silently discarded. This results in invalid model, which, when deployed and queried, causes the following error in the server log:

    Connector worker process failed for atomic-request=AVU37BnZoOUS.0.0.0: org.teiid.translator.TranslatorException: TEIID23007 OPTIONS property CELL_NUMBER is required and it not defined on column ROW_ID

The DDL obtained from the server is

When trying to import the same DDL using the DDL import wizard, a warning dialog is shown stating that the extension properties could not be processed and the Model Extension Definition should be registered
