This is a new version and is not an "upgrade"
Your old settings and configurations are not carried over to the new plugin.
The old version
Had 2 parameters stored in the database.
Custom Name, and the dropstring
custom_drop_name="Color"|custom_drop="Choose Color,Arizona, Autumn, Black, Brushed Silver, Dark Mahogany, Light Oak, Light Stone, Maple, Stone, Teak"|
BUT! The new version has it stored
custom_drop="Choose Color,Arizona, Autumn, Black, Brushed Silver, Dark Mahogany, Light Oak, Light Stone, Maple, Stone, Teak"|
for the old customs to work with the new dropbox,
you have to remove EVERYTHING BEFORE custom_drop=
FOR ME, THIS FIXED ALL OF THE CUSTOMS,
UPDATE `xxx_virtuemart_product_customfields` SET `customfield_params` = SUBSTRING_INDEX(`customfield_params`,'|',-2);
AS WELL AS WHATS POSTED HERE.https://forum.virtuemart.net/index.php?topic=127362.msg436581#msg436581
