Hi guys,I have the same problem, but only on the client open ticket page.This only happens with a custom fiel with dropdown or multiple selection on the Contact information form.Example a list with all the countries for the client to define his origin.I've been trying to find a solution for this, but until now I was not able to get it.Tested in the new 1.10 RC2 and it works.This only started to occur after the upgrade to 1.9.12.Tested a clean install and the problem always occurs every time I open a ticket.After I open the ticket I'm able edit the field that was inserted as blank and define the correct value, so this is being a problem only on the open ticket form in the client side.I hope this information can help.Hope someone can help.Best Regards,
