Error when deleting feature group

Hello,

I tried deleting two feature groups yesterday, but got impatient and closed the window before it was finished processing the request (Stupid, I know).
Now I can still see the two feature groups in the overview, but when I try opening them, the screen just shows a loading hopsworks logo. Furthermore, if I try using the “get_or_create_feature_group” command, I get the following error:

Metadata operation error: … Server response: HTTP code: 500, HTTP reason: Internal Server Error, body: b’{“errorCode”:270116,“usrMsg”:“Error getting feature group table from Hive Metastore: hive.xxx_featurestore.xxx table not found”

I need to delete them, as I’m using the free version of Hopsworks with a limit of 5 online feature groups.

Does anyone know, how I can delete the feature group in a different way?
