Copy Invoice - Submit Button does nothing - Client Name does not populate from copied invoice

CENTOS 6.9 x86_64 virtuozzo
php56
InvoicePlane 1.5.3
MySQL 5.5

After opening an invoice and choosing Copy Invoice from the Options menu, the following problems occur:

  1. Client field is blank. I must search for and select the client. (this behavior is different from previous version 1.4.9)
  2. Clicking submit appears to do nothing, however for each click of the button an invoice is created in the background. Must click cancel and view invoices to see newly copied invoices…
