Have you gone through Basic debugging checklist? Sounds like you've now done part (using the debugger), but maybe not everything: Does your $opts{defaults} really contain what you think it does when it enters the sub you showed? If not, then the problem lies outside of what you've shown. If it does contain what you think it should, then give us a security-redacted version of $opt{defaults}, because we cannot debug your logic in that sub without knowing what's there. See also SSCCE, How to ask better questions using Test::More and sample data, and How do I change/delete my post?

edit: add "everything": I had intended the "but maybe not: ..." to be one logical thought, separate from "you've now done part"... but when re-reading, it looked more like I was saying OP hadn't done even the running-the-debugger, which was not what I meant. sorry. /edit
