Hi AgitatedDove14 ,
right now i can delete, i set configuration to see hidden project/file on UI, and it show task related (e.g pipeline, dataset) on that project. but yeah, every time i make project with subproject inside, there is [undefined] there. i create project using code and UI, the result is same.

this is my docker-compose conf. i change all port 8XXX to 7XXX nad also change /opt/cleaml to /mnt/hdd_2/clearml.
