Noticed a little bug in the vendors input fields. There are missing length attributes.
If you put more then 20 characters into the phone or fax field, it will be cut off on save.
as example
+49 (0)7612 345 67 89
will be saved as
+49 (0)7612 345 67 8
I just tested the fields phone and fax. Didn't test the other fields.
