Hi Hellion,
I am not sure what is happening it would take a hugh amount of logging to have the need to delete when limit is reached with those settings.
Even if this limit was reached, I would expect it to only get deleted when more logs were created therefore I would expect some to be showing at all times ???.
If in doubt set it to save full logs to a specific location and see what happens, you can always delete these after if no longer required.
Sorry I am not much help here, if anyone else has some suggestions please do so.
Thanks.
Kind regards.
