Running out of Space

I use this Docker Install which is pretty basic, it just allows for nginx use and OnlyOffice. I prefer OnlyOffice vs Collabora, and not really wanting to change that. Anyways. It all installs fine and works. So I migrated my data from a previous Nextcloud install and even though I have 800Gb for my Docker machine, and I migrated 56Gb from my old machine, It says I am running out of space. So after doing some research I did “df -h --total” in my command line and it shows me:

overlay                             98G   90G  3.3G  97% /var/lib/docker/overlay2/215ae8c0afd1def91650ffdb7a80cea6a69a020969088bb806a047629d38d401/merged

When I close the containers these disappear. I know that the image I use has 3 stacked containers. One for the OnlyOffice, one for NGINX, and one for Nextcloud. I have my data volume for Nextcloud binded to a folder on the host machine but I still get this issue.

Any Ideas?
