after update - city and address_1 are "missing" when clicking on "order confirma

[ydl]

Joomla 3.6.3 and updating to VM 3.0.18

I have 'address_1' and 'city' fields are mandatory...  and  exist in the user profile

In the shopping cart when trying to confirm  the order an error message about missing parameters appears.

Whet I saw (with some debug prints) the the 'cartfields' info (administrator\components\com_virtuemart\models\user.php around line 765...) I am geting:
array (size=5)
  'customer_note' => string '' (length=0)
  'tos' => string '1' (length=1)
  'address_1' => string '' (length=0)
  'zip' => string '' (length=0)
  'city' => string '' (length=0)

which, I believe, cause the problem...

any idea how to solve it?
