Can't delete builder

Hi,

I can’t delete my builder for a day, keeps saying to me:

Error unhandled upstream service error: error renaming lv: error creating volume:   Existing logical volume "app_110801_machine_data_45131" not found in volume group "data_0"
: exit status 5

Not sure how could I mitigate this, tried CLI and GUI to no avail.

Cheers,
Daniel
