Why do all the channels of the analog input module 6ES7331-1KF02-0AB0 show an overflow even though the wiring regulations have been complied with?

Description
If you configure the analog input module 6ES7331-1KF02-0AB0 in the STEP 7 project using STEP 7 V 5.4 and HW Update (HSP2067), then you must note that any analog input module already configured on that slot will be deleted and not just copied over. If a module to be exchanged is not deleted beforehand, the analog input module 6ES7331-1KF02-0AB0 shows an overflow on all the channels even if the wiring regulations have been complied with.
