Rsyc transfers - out of sync? ( days behind)

I have incremental backups working to a remote server via rsync ( a QNAP in this case). I have daily x 7, weekly x 3 monthly x 3. This has been working fine for a while (years). Recently the WHM server storage hit 95+% and this stopped backups working until I resized the disk and created more space. To 'catch up' on backups I immediately ran a manual back up. Once complete through on the remote storage I could not see the daily folder made of remote incremental files. I waited until the next day, and not seeing the current date I manually ran the backup again .. same thing. Leaving it a few days over the weekend I thought it might 'shake itself out', and then watching a few more it does seem to have 'daily' uploaded folders just a few days behind the current date. When I look in this last modified folder most data is dated 2 days ago with a few items showing todays date as modify - but certainly the named date of the last daily sync folder is two days behind. On my WHM server in /home/backups/ I see the following folders ( daily backups and monthly - today is the 11th) 2022-10-11 2022-10-10 2022-10-09 2022-10-02 2022-09-17 2022-09-02 monthly monthly/2022-07-15 monthly/2022-08-15 monthly/2022-09-15 weekly weekly/2022-09-25 weekly/2022-10-02 weekly/2022-10-09 Firstly - I thought this data was removed after a completed backup. So I'm surprised to see multiple days here... some jumping back a bit. On the remote server ( just recent folders ) 2022-10-09 ( last modified of this folder is the 11th) 2022-10-08 ( last modified of this folder is the 10th) 2022-10-07 ( last modified of this folder is the 09th) .. and so on I'm wondering how to fix this... it there is simply a way to run the rsync a few times so it catches up? How to be sure the local backups are cleaned up properly. OR ... I'm happy to clear it all out and start a fresh sync - but I'm not sure on the best way to do this either.
