Hi @<1547028031053238272:profile|MassiveGoldfish6>
hmm yeah you need to remove the "hidden" system_tag from the project

from clearml.backend_api.session.client import APIClient

c = APIClient()

print(c.projects.get_by_id("PROJECT_ID_HERE").to_dict())

c.projects.update(project="PROJECT_ID_HERE", system_tags=["test"])

print(c.projects.get_by_id("PROJECT_ID_HERE").to_dict())

Notice you can get the project ID from the URL
/projects/1974af8ccdac454b836c47349c4e826e/experiments/845ba08b08154e1794829b92a7136746/execution?
here the 1974af8ccdac454b836c47349c4e826e is the project id

Thank you so much, it worked :D

Woot woot 🎊
