Same Reference Number Being Used for Different Sources and Reference List Restarting Partway Through

I'm having trouble with my in text references and bibliography list. The reference list appears to be glitching for some reason and adding the same number to different citations. I am using AMA style and have automatic citation updates selected in the document preferences. I noticed this issue before so deleted all references and started fresh by manually inputting each again. The same issue occurred.

Here is the bibliography list. You can see that there are two different sources for #2 and the list goes 1-8 before restarting at 3-19.
