Problem with adding new clients after update

[bolero]

I tried to add a new client as a reseller after updating to 2.2.24 and that fails because it requires a title. It's impossible to not enter a title with that dropdown being present. No matter if I set that field to required or not it asks to "enter a value in the field 'title'". As I was able to add new clients yesterday before the update I think the problem must be related to the update. Updating existing clients works.
