VW PQ: overlapping signals in DBC

I tried importing the DBC with cantools(https://pypi.org/project/cantools/) however i got following errors:
cantools.database.errors.UnsupportedDatabaseFormatError: DBC: "The signals Timeout_Bremsenbotschaft and Indiziertes_Istmoment__Slave_ are overlapping in message Slave_1."
cantools.database.errors.UnsupportedDatabaseFormatError: DBC: "The signals Pumpentemperatur__3_2_2_ and Zylinderzaehler__3_2_2_ are overlapping in message PSG_1."
cantools.database.errors.UnsupportedDatabaseFormatError: DBC: "The signals BSK_BT_geoeffnet and GK1_Count_Anhaen are overlapping in message Gate_Komf_1."
cantools.database.errors.UnsupportedDatabaseFormatError: DBC: "The signals BSK_HD_Hauptraste and GK1_Count_Anhaen are overlapping in message Gate_Komf_1."
cantools.database.errors.UnsupportedDatabaseFormatError: DBC: "The signals Frei_Fahrwerk_1_1 and Einstellung_Fahrwerkdaempfung_4 are overlapping in message Fahrwerk_1."

I deleted the conflicting signals and it started working. Not sure which of the signals are defined wrong or its a bug of cantools. Wanted to report before someone struggles
