Dear Armin, thanks for reporting back. There really might be a problem with converting the config file between BIT 1.2.1 and 1.3.3. I have to investigate this further and try to reproduce it.
It might be a serious problem to everyone upgrading from Debian 11 to 12 and using "Repeatedly (anacron)" as schedule option. Do you still have access to your old config file from BIT version 1.2.1? This would be really helpful. If not can you tell me exactly how do you setup your profile with BIT 1.2.1? It was setup to "Repeatedly (anacron)"? Each N hours/days/weeks/months? Was it a local/local (encrypted)/SSH/SSH (encrypted) profile? Thanks in advance Christian
