deleting odd, out of sequence number then deletes my whole bibliography

Here a screen grab of my text:

The 1 that is out of sequence in line 4 removes my bibliography of 35 items if I delete it. When I show field codes (Mac: OPT+FN+F9), the codes show for the 16,29-33 references, but no codes for the 1. In show codes mode, if I hover over the 1, a pop up shows: ADDIN ZOTERO_BIBL {“uncited”:[],“omitted”:[],“custom”:[]} CSL_BIBLIOGRAPHY
I tried several strategies for deleting the 1 provided by a Chrome AI search, to no avail. Any advice for how to get rid of the 1?
