SharePoint Syntex not tagging managed metadata terms from Synoyms

Question

I am trying to use SharePoint Syntex to automatically add tags based on content.

I have a managed metadata column that is mapped to a term set. Some of these terms have synonyms defined.

When the extractor identifies the labels, that are exactly matching the terms, it is adding them to the column, however when the label is defined in the synonym for a term, the term is not getting added to the column value.

Any help would be appreciated
