YouTube Extension - VM Prodcut Page Warning

When I use the Youtube Plugin, I get the following error on the Product Custom Field Page:

Warning: Invalid argument supplied for foreach() in /home/username/public_html/mywebsite.com/administrator/components/com_virtuemart/plugins/vmcustomplugin.php on line 100

It doesn't seen to affect anything but do we know why this would happen?

Hi,

The issue is fixed in the latest version, It will be available after within 5 hours. You can download it after logging into your account.

It's now available. The version is 1.0.1

Thanks for making an update for the issue, however the update has made a larger problem. When I go to the custom fields tab on the product page, the fields are now all blank. See attached. If I save, I loose all of the video information. If I go to the site page, the video information is gone as well. What could be causing this?
