Generated linkml schema has title in range instead of name

[sujaypatil96]

When we were trying to generate the linkml schema for GA4GH VA in this repo: ga4gh-va, and you look at the source schema here, you'll see when the range for some induced slots were populated with their title, i.e., space separated names rather than their name.

For example: for induced slot variability in the schema, range gets populated as Data Item instead of DataItem.
