In review of the commit history based on that date range and the changes made, the suggestion would be to 1) download the current (updated today) version, 2) run the install again, 3) not remove the plugin (without backup of the products_with_attributes_stock table) if desired to continue using the variants previously created.
Rerunning the install will reset the SBA associated admin configuration options applied, but will also update the database to contain changes incorporated between those dates that have a potential to affect the option name type added by SBA to provide javascript related information when product have a single option name.
