The funds are for functions other than immigration enforcement and customs enforcement
What the document says“except that funds provided in this section shall be used for functions other than those related to Homeland Security Investigations' immigration enforcement and customs enforcement missions.”
The closing clause confines the whole appropriation. The funds provided in this section are to be used for functions other than those related to the immigration enforcement and customs enforcement missions of Homeland Security Investigations. The same limit appears on the other appropriations in title I.
What the document actually says“except that funds provided in this section shall be used for functions other than those related to Homeland Security Investigations' immigration enforcement and customs enforcement missions.”

Title I of this law is for work that is not immigration work. Title II is for that work. The two halves of the law are kept apart this way.
