Wrong error message for project create page

[jozef-budac]

When I am adding a field with the same name, there is a correct error message, that the 2nd field with the same name as the previous one will not be added.
What is strange, is that this error appears also for 2 field names "Num" and "Num33". The number behind the name is somehow ignored. But anyway, the field is added to the project regardless of the error message.
