All dates containing underscores should be literal
A recommended workaround for date ranges is to use an underscore as range separator and later replace it manually (pandoc even does this automatically).
However, not all dates with underscores are parsed and exported as literal, including ranges with months and days.
My suggestion: _all_ date fields containing underscores should be parsed and exported as literal dates. No known regular date format contains underscores, so one that does quite clearly cannot be a regular date.

However, my current suggestion is merely about a quick fix of the inconsistency in how Zotero parses and exports date fields containing underscores.
