Multiple backups daily, what’s wrong?

Hi, I’m using this plugin in several websites and the backups are set to be done daily for DB (saving 5 copies) and fortnightly for the entire site (saving 2 copies), all the files are saved on a Google Drive folder and deleted automatically from the server after this is done. The problem is that sometimes this doesn’t work as expected and I end up with a bunch of backups on the same day, as shown below (this is just one of the websites):

There have been 8 DB backups each day in the last 2 days.

I’ve installed the WP Control plugin and the Cron Events seems to be ok, it only shows two events related to Updraft as far as I can see:

This is the latest backup log available: https://docs.google.com/document/d/11YxF_4ouRX9YBl7XF1MZwhfAFLWCFej-rVfiHDkWDs4/edit?usp=sharing

Lastly, sometimes this also happens on other sites where I’m using the Pro version, but not right now.

I appreciate any guidance to solve this issue.

Thanks.
