Question - Custom Field Dropdown List is not catching items

Hi all,

I’m creating a new dropdown list and when as follows:

And if I try to add the value “Annual” the system is not catching it. But if I try to add other value (i.e. “-Annual”) it works, also if I remove “Biannual” I can add “Annual”.


I can not reproduce this error. the only thing which happened to me is that when i was typing annual browser already give me biannual so i needed to choose annual. May this be the case?
