Not finding all changesets from a user

[Fizzie41]

I'm submitting a (bug report/question)

Not sure if this is a bug, or possibly something wrong with my search parameters?

Brief Description

As part of DWG monitoring, I use an OSMCha filter, set to search for New Mappers who have made Mass Modifications, using these parameters:
Date - manually entered as yesterday or today
Location - any
Reasons for flagging - "New mapper" AND "Mass modification"
Hide trusted users - Yes
Objects created - 0-0
Objects modified - 20
Objects deleted - 0-0

What is the current behaviour, (attach relevant screenshots) ?

It usually works well e.g. https://osmcha.org/changesets/140692433?filters=%7B%22date__gte%22%3A%5B%7B%22label%22%3A%222023-09-01%22%2C%22value%22%3A%222023-09-01%22%7D%5D%2C%22delete__lte%22%3A%5B%7B%22label%22%3A%220%22%2C%22value%22%3A%220%22%7D%5D%2C%22create__lte%22%3A%5B%7B%22label%22%3A%220%22%2C%22value%22%3A%220%22%7D%5D%2C%22modify__gte%22%3A%5B%7B%22label%22%3A%2220%22%2C%22value%22%3A%2220%22%7D%5D%2C%22delete__gte%22%3A%5B%7B%22label%22%3A%220%22%2C%22value%22%3A%220%22%7D%5D%2C%22create__gte%22%3A%5B%7B%22label%22%3A%220%22%2C%22value%22%3A%220%22%7D%5D%2C%22hide_whitelist%22%3A%5B%7B%22label%22%3A%22Yes%22%2C%22value%22%3A%22True%22%7D%5D%2C%22all_reasons%22%3A%5B%7B%22label%22%3A%22New%20mapper%22%2C%22value%22%3A40%7D%2C%7B%22label%22%3A%22mass%20modification%22%2C%22value%22%3A4%7D%5D%7D

But occasionally it doesn't find all the changesets created by that user, despite them also being flagged with the same reasons e.g. https://osmcha.org/changesets/140692068?filters=%7B%22date__gte%22%3A%5B%7B%22label%22%3A%22%22%2C%22value%22%3A%22%22%7D%5D%2C%22ids%22%3A%5B%7B%22label%22%3A%22140692068%22%2C%22value%22%3A%22140692068%22%7D%5D%7D

Could this be caused by an error in my parameters?
