Few issues with purchase orders

[MacPhotoBiker]

I just recently upgraded to version 4.11.0. When processing purchase orders, I'm finding the following issues:

1) When creating a purchase order based on a sales order, I get a confirmation that the PO was created. However, when I try to print it, I get "PO can not be located" (we had this issue also in 4.10)

2) When creating a PO from scratch, it's now more restrictive than before on the phone number. I usually put the area code in brackets for better readability, but I now get "please match the format requested". I understand that usually input patterns should be rather restrictive, but disallowing brackets in phone numbers is maybe a bit too resctrictive
