Ghost template or repository errors

Hi, i have a lot of errors

level : ERROR
action : load
Parameters : Pydio\Core\Model\FilteredRepositoriesList
More : Disabling repository as parent cannot be correctly loaded

Pydio 8.0.2
Ubuntu 16.04 LTS
Apache 2

I think this is a ghoist template or wrkspace but i don’t know how to remove it

Any idea ?

Thank you !
