Why do I not find some changesets when filtering changesets on OSMCha?

I am having some trouble using OSMCha. I would like to search for all changesets since 1st Oct which used NVE Electricity Network overlay as a source (here it is in ELI, JOSM). I go here, set 2 search fields: Date to 2024-10-01, Source to NVE Electricity Network overlay. I click Apply, I get the result:

Only 1 changeset. I think there are more changesets which satisfy the criteria, for example this one:

(I don’t think it should matter, but this seemingly missed changeset was done by me.)

Why am I not finding all changesets satisfying the criteria?
