RT3.3 Custom Field bug?

I-ve upgraded to 3.3.10 (from 3.2.2).
I-ve created a new CustomField, assigned it to Users and selected a User
Then I changed the type to
"select multiple values"
clicked submit
got the input fields for the first value, but in the type field “Enter
multiple values” appeard. Changed this again to “Select…”,
filled in the value fileds and clicked on submit. Then I got the message:

CustomField 3: TypeComposite: That is already the current value

It seems, like only “Enter multiple values is accepted”.

Another Question:
Why is there no “Enter one value” or “select one value” ? Any reason?
